Mozilla
Firefox
Firefox
(or simply Firefox) is a free and open-source[20] web browser developed by Mozilla Foundation
Mozilla Foundation
and its subsidiary, Mozilla Corporation. Firefox
Firefox
is available for Windows, macOS, Linux, and BSD[10][11] operating systems. Its sibling, Firefox
Firefox
for Android, is available for Android. Firefox
Firefox
uses the Gecko layout engine to render web pages, which implements current and anticipated web standards.[21] An additional version, Firefox
Firefox
for iOS, was released in late 2015; due to platform restrictions, it uses the WebKit
WebKit
layout engine instead of Gecko, as with all other iOS web browsers. Firefox
Firefox
was created in 2002 under the codename "Phoenix" by the Mozilla
Mozilla
community members who desired a standalone browser, rather than the Mozilla Application Suite
Mozilla Application Suite
bundle. During its beta phase, Firefox
Firefox
proved to be popular with its testers and was praised for its speed, security, and add-ons compared to Microsoft's then-dominant Internet Explorer 6. Firefox
Firefox
was released in November 2004,[22] and challenged Internet Explorer's dominance with 60 million downloads within nine months.[23] Firefox
Firefox
is the spiritual successor of Netscape Navigator, as the Mozilla
Mozilla
community was created by Netscape
Netscape
in 1998 before their acquisition by AOL.[24] Firefox
Firefox
usage grew to a peak of 32% at the end of 2009,[25] temporarily making version 3.5 the world's most popular browser.[26][27] Usage then declined in competition with Google Chrome.[25] As of March 2018[update], Firefox
Firefox
has 11.6% usage share as a "desktop" browser, according to StatCounter, making it the second most popular such web browser;[28][29][30][31] usage across all platforms is lower at 5.44% (and then 4th most popular overall). Firefox
Firefox
is still the most popular desktop browser in Cuba (even most popular overall at 62.77%[32]) and Eritrea
Eritrea
with 78.3%[33] and 82.96%[34] of the market share, respectively. According to Mozilla, as of December 2014[update] there were half a billion Firefox
Firefox
users around the world.[35]

History[edit] Main article: History of Firefox The Firefox
Firefox
project began as an experimental branch of the Mozilla project by Dave Hyatt, Joe Hewitt, and Blake Ross. They believed the commercial requirements of Netscape's sponsorship and developer-driven feature creep compromised the utility of the Mozilla
Mozilla
browser.[36] To combat what they saw as the Mozilla
Mozilla
Suite's software bloat, they created a stand-alone browser, with which they intended to replace the Mozilla
Mozilla
Suite.[37] On April 3, 2003, the Mozilla
Mozilla
Organization announced that they planned to change their focus from the Mozilla Suite to Firefox
Firefox
and Thunderbird.[38] The community-driven SeaMonkey was formed and eventually replaced the Mozilla Application Suite
Mozilla Application Suite
in 2005.

The Firefox
Firefox
project has undergone several name changes.[39][40][41][42][43][44][45][46] It was originally titled Phoenix, which carried the implication of the mythical firebird that rose triumphantly from the ashes of its dead predecessor, in this case from the "ashes" of Netscape Navigator
Netscape Navigator
after it had been killed off by Microsoft
Microsoft
Internet Explorer
Internet Explorer
in the "First browser war". Phoenix was renamed due to trademark issues with Phoenix Technologies; the replacement name, Firebird, provoked an intense response from the Firebird database software project.[47][48] In response, the Mozilla Foundation stated that the browser would always bear the name Mozilla Firebird to avoid confusion. After further pressure, on February 9, 2004, Mozilla
Mozilla
Firebird became Mozilla
Mozilla
Firefox.[49] The name Firefox was said to be derived from a nickname of the red panda,[50][51] which became the mascot for the newly named project. For the abbreviation of Firefox, Mozilla
Mozilla
prefers Fx or fx, though it is often abbreviated as FF.[52] The Firefox
Firefox
project went through many versions before the version 1.0 was released on November 9, 2004. In 2016, Mozilla
Mozilla
announced a project known as Quantum, which sought to improve Firefox's Gecko engine and other components in order to improve Firefox's performance, modernize its architecture, and transition the browser to a multi-process model. These improvements came in the wake of decreasing market share to Google
Google
Chrome, as well as concerns that its performance was lapsing in comparison. Despite its improvements, these changes required existing add-ons for Firefox to be made incompatible with newer versions, in favor of a new extension system that is designed to be similar to Chrome and other recent browsers. Firefox
Firefox
57, which was released in November 2017, was the first version to contain enhancements from Quantum, and has thus been named Firefox
Firefox
Quantum. A Mozilla
Mozilla
executive stated that Quantum was the "biggest update" to the browser since version 1.0.[53][54][55] Features[edit] Main article: Features of Firefox Features include tabbed browsing, spell checking, incremental find, live bookmarking, Smart Bookmarks, a download manager, private browsing, location-aware browsing (also known as "geolocation") based on a Google
Google
service,[56] and an integrated search system, which uses Google
Google
by default in most markets.[57] Additionally, Firefox
Firefox
provides an environment for web developers in which they can use built-in tools, such as the Error Console or the DOM Inspector, or extensions, such as Firebug and more recently there has been an integration feature with Pocket. Firefox
Firefox
Hello was an implementation of WebRTC, added in October 2014, which allows users of Firefox
Firefox
and other compatible systems to have a video call, with the extra feature of screen and file sharing by sending a link to each other. Firefox
Firefox
Hello is scheduled to be removed in September 2016.[58] Functions can be added through add-ons created by third-party developers. Add-ons are primarily coded using an HTML
HTML
and JavaScript API known as WebExtensions, which is designed to be similar to the Google Chrome
Google Chrome
and Microsoft
Microsoft
Edge extension systems. Firefox
Firefox
previously supported add-ons using the XUL and XPCOM APIs, which allowed them to directly access and manipulate much of the browser's internal functionality. As they are not compatible with its multi-process architecture, XUL add-ons are now deemed Legacy add-ons and are no longer supported on Firefox
Firefox
57 and newer.[59][60] Firefox
Firefox
can have themes added to it, which users can create or download from third parties to change the appearance of the browser. The Firefox
Firefox
add-on website also gives users the ability to add other applications such as games, ad-blockers, screenshot apps, and many other apps.[61][62] Standards[edit]

Firefox
Firefox
implements many web standards, including HTML4
HTML4
(almost full HTML5), XML, XHTML, MathML, SVG 2 (partial),[63][64] CSS (with extensions),[65] ECMAScript (JavaScript), DOM, XSLT, XPath, and APNG (Animated PNG) images with alpha transparency.[66] Firefox
Firefox
also implements standards proposals created by the WHATWG
WHATWG
such as client-side storage,[67][68] and canvas element.[69] These standards are implemented through the Gecko layout engine, and Spidermonkey JavaScript
JavaScript
engine. Firefox
Firefox
has passed the Acid2
Acid2
standards-compliance test since version 3.0.[70] Mozilla
Mozilla
had originally stated that they did not intend for Firefox
Firefox
to pass the Acid3
Acid3
test fully because they believed that the SVG fonts part of the test had become outdated and irrelevant, due to WOFF being agreed upon as a standard by all major browser makers.[71] Because the SVG font tests were removed from the Acid3
Acid3
test in September 2011, Firefox
Firefox
4 and greater scored 100/100.[72][73] Firefox
Firefox
also implements "Safe Browsing",[74] a proprietary protocol[75] from Google
Google
used to exchange data related with phishing and malware protection. Since version 38 on Windows
Windows
Vista and newer, Firefox
Firefox
supports the playback of video content protected by HTML5
HTML5
Encrypted Media Extensions (EME). For security and privacy reasons[which?], EME is implemented within a wrapper of open source code that allows execution of a proprietary DRM module by Adobe Systems—Adobe Primetime Content Decryption Module (CDM). CDM runs within a "sandbox" environment to limit its access to the system, and provide it a randomized device ID to prevent services from uniquely identifying the device for tracking purposes. The DRM module, once it has been downloaded, is enabled and disabled in the same manner as other plug-ins. Since version 47,[76] "Google's Widevine CDM on Windows
Windows
and Mac OS X so streaming services like Amazon Video
Amazon Video
can switch from Silverlight
Silverlight
to encrypted HTML5 video" is also supported.

Firefox
Firefox
downloads and enables the Adobe Primetime and Google
Google
Widevine CDMs by default to give users a smooth experience on sites that require DRM. Each CDM runs in a separate container called a sandbox and you will be notified when a CDM is in use. You can also disable each CDM and opt out of future updates — Watch DRM content on Firefox[77]

and that it is "an important step on Mozilla's roadmap to remove NPAPI plugin support. "[78] Upon the introduction of EME support, builds of Firefox
Firefox
on Windows
Windows
were also introduced that exclude support for EME.[79][80] Security[edit] See also: Browser security Firefox
Firefox
allowed for a sandbox security model to manage privileges accorded to JavaScript
JavaScript
code, but that feature has since been deprecated.[81] It limits scripts from accessing data from other websites based on the same-origin policy.[82] It also provides support for smart cards to web applications, for authentication purposes.[83] It uses SSL/TLS to protect communications with web servers using strong cryptography when using the HTTPS
HTTPS
protocol.[84] The freely available HTTPS Everywhere add-on enforces HTTPS, even if a regular HTTP URL is entered. Firefox
Firefox
now supports HTTP/2.[85] The Mozilla Foundation
Mozilla Foundation
offers a "bug bounty" (US$3,000 to US$7,500 cash reward) to researchers who discover severe security holes in Firefox.[86] Official guidelines for handling security vulnerabilities discourage early disclosure of vulnerabilities so as not to give potential attackers an advantage in creating exploits.[87] Because Firefox
Firefox
generally has fewer publicly known security vulnerabilities than Internet Explorer
Internet Explorer
(see Comparison of web browsers), improved security is often cited as a reason to switch from Internet Explorer
Internet Explorer
to Firefox.[88][89][90][91] The Washington Post reported that exploit code for known critical security vulnerabilities in Internet Explorer
Internet Explorer
was available for 284 days in 2006. In comparison, exploit code for known, critical security vulnerabilities in Firefox
Firefox
was available for nine days before Mozilla
Mozilla
issued a patch to remedy the problem.[92] A 2006 Symantec
Symantec
study showed that, although Firefox
Firefox
had surpassed other browsers in the number of vendor-confirmed vulnerabilities that year through September, these vulnerabilities were patched far more quickly than those found in other browsers—Firefox's vulnerabilities were fixed on average one day after the exploit code was made available, as compared to nine days for Internet Explorer.[93] Symantec
Symantec
later clarified their statement, saying that Firefox
Firefox
still had fewer security vulnerabilities than Internet Explorer, as counted by security researchers.[94] In 2010 a study of the National Institute of Standards and Technology (NIST), based on data compiled from the National Vulnerability Database (NVD), Firefox
Firefox
was listed as the fifth most vulnerable desktop software, with Internet Explorer
Internet Explorer
as the eighth, and Google Chrome as the first.[95] InfoWorld
InfoWorld
has cited security experts saying that, as Firefox
Firefox
becomes more popular, more vulnerabilities will be found,[96] a claim that Mitchell Baker, president of the Mozilla
Mozilla
Foundation, has denied. "There is this idea that market share alone will make you have more vulnerabilities. It is not relational at all," she said.[97] In October 2009, Microsoft's security engineers acknowledged that Firefox
Firefox
was vulnerable to a security issue found in the 'Windows Presentation Foundation' browser plug-in since February of that year. A .NET Framework
.NET Framework
3.5 SP1 Windows
Windows
Update had silently installed the vulnerable plug-in into Firefox.[98] This vulnerability has since been patched by Microsoft.[99] As of February 11, 2011, Firefox
Firefox
3.6 had no known unpatched security vulnerabilities according to Secunia.[100] Internet Explorer
Internet Explorer
8 had five unpatched security vulnerabilities, the worst being rated "Less Critical" by Secunia.[101] Mozilla
Mozilla
claims that all patched vulnerabilities of Mozilla
Mozilla
products are publicly listed.[102] On January 28, 2013, Mozilla
Mozilla
was recognized as the most trusted internet company for privacy in 2012.[103] This study was performed by the Ponemon Institute and was a result of a survey from more than 100,000 consumers in the United States. In February 2013, plans were announced for Firefox
Firefox
22 to disable third-party cookies by default. However, the introduction of the feature was then delayed so Mozilla
Mozilla
developers could "collect and analyze data on the effect of blocking some third-party cookies." Mozilla
Mozilla
also collaborated with Stanford University's "Cookie Clearinghouse" project to develop a blacklist and whitelist of sites that will be used in the filter.[104][105] Version 23, released in August 2013, followed the lead of its competitors by blocking iframe, stylesheet, and script resources served from non- HTTPS
HTTPS
servers embedded on HTTPS
HTTPS
pages by default. Additionally, JavaScript
JavaScript
could also no longer be disabled through Firefox's preferences, and JavaScript
JavaScript
was automatically re-enabled for users who upgraded to 23 or higher with it disabled. The change was made due to its use across the majority of websites, the potential repercussions on non-experienced users who are unaware of its impact, along with the availability of extensions such as NoScript, which can disable JavaScript
JavaScript
in a more controlled fashion. The following release added the ability to disable JavaScript
JavaScript
through the developer tools for testing purposes.[106][107][108] In January 2015, TorrentFreak
TorrentFreak
reported that using Firefox
Firefox
when connected to the internet using a VPN can be a serious security issue due to the browser's support for WebRTC.[109] Beginning with Firefox
Firefox
44 (2016), all extensions must be signed by Mozilla
Mozilla
to be used in release and beta versions of Firefox. Firefox
Firefox
43 blocked unsigned extensions, but allowed enforcement of extension signing to be disabled. All extensions must be submitted to Mozilla Add-ons and be subject to code analysis in order to be signed, although extensions do not have to be listed on the service in order to be signed.[110][111] In Firefox
Firefox
versions prior to 7.0, an information bar appears on the browser's first start asking users whether they would like to send performance statistics, or "telemetry", to Mozilla. It is enabled by default in development versions of Firefox, but not in release versions.[112] According to Mozilla's privacy policy,[113] these statistics are stored only in aggregate format, and the only personally identifiable information transmitted is the user's IP address. As of 2016[update], Firefox
Firefox
is the last widely used browser not to use a browser sandbox to isolate Web content in each tab from each other and from the rest of the system.[114] Version 50 includes a limited sandbox that isolates the content rendering process (separated thanks to the Electrolysis project), which will be progressively enhanced to improve security.[114][115] Localizations[edit] Main article: Mozilla
Mozilla
localizations Firefox
Firefox
is a widely localized web browser. The first official release in November 2004 was available in 24 different languages and for 28 locales, including British English, American English, European Spanish, Argentine Spanish, and Chinese in Traditional Chinese characters and Simplified Chinese characters.[116] As of March 2018[update], currently supported versions 59.0.2 and 52.7.3esr are available in 89 locales (79 languages).[17] Platform availability[edit] The desktop version of Firefox
Firefox
is available and supported for Windows, macOS and Linux, while Firefox
Firefox
for Android is available for Android (formerly Firefox
Firefox
for mobile, it also ran on Firefox
Firefox
OS).

because the rendering engines used in both browsers are the same.[145] Version 7 was the last release for Maemo

said that Firefox

Mozilla
was that prior to iOS 8, Apple had supplied third-party browsers with an inferior version of their JavaScript

performance on the iOS platform.[148] Apple later opened their "Nitro" JavaScript

Notes

Firefox
Firefox
for iOS is not listed in this table as its version numbers would be misleading; it uses version numbers that do not correspond to any of the other Firefox
Firefox

Unofficial ports[edit] Firefox
Firefox
has also been ported to FreeBSD,[159] NetBSD,[160] OpenBSD,[161] OpenIndiana,[162] OS/2[163] and SkyOS, and an unofficial rebranded version called Timberwolf has been available for AmigaOS 4. An unofficial continuation of the macOS PowerPC

§ Extended Support Release, and Long-term support Besides official releases, Mozilla
Mozilla
provides development builds of Firefox
Firefox
in distribution channels named, in order of most to least stable, "Beta", "Developer Edition" (former "Aurora", renamed on November 10, 2014[173][174]), and "Nightly". As of March 13, 2018[update], Firefox
Firefox
60 is in the "Beta" and "Developer Edition" channel, and Firefox
Firefox
61 is in the "Nightly" channel.[175] Starting from Firefox
Firefox
54, "Developer Edition" is based on the "Beta" build.[176] Firefox
Firefox
Extended Support Release, abbreviated to ESR, is a version of Firefox
Firefox
for organizations and other groups that need extended support for mass deployments. Each ESR release, based on the regular version released at the same time, is supported for approximately one year.[177] Unlike the regular ("rapid") releases, ESRs are not updated with new features and performance enhancements every six weeks, but rather are updated with only high-risk-reduction or high-impact security fixes or major stability fixes with point releases, until the end of the ESR cycle.[178] Licensing[edit] Firefox
Firefox
source code is free software, with most of it being released under the Mozilla Public License
Mozilla Public License
(MPL) version 2.0.[19] This license permits anyone to view, modify, or redistribute the source code. As a result, several publicly released applications have been built from it, such as Netscape, Flock, Miro, GNU IceCat, Iceweasel, Songbird, Pale Moon, and Comodo IceDragon. In the past, Firefox
Firefox
was licensed solely under the MPL, then version 1.1,[179] which the Free Software Foundation
Free Software Foundation
criticized for being weak copyleft, as the license permitted, in limited ways, proprietary derivative works. Additionally, code only licensed under MPL 1.1 could not legally be linked with code under the GPL.[180][181] To address these concerns, Mozilla
Mozilla
re-licensed most of Firefox
Firefox
under the tri-license scheme of MPL 1.1, GPL 2.0, or LGPL 2.1. Since the re-licensing, developers were free to choose the license under which they received most of the code, to suit their intended use: GPL or LGPL linking and derivative works when one of those licenses is chosen, or MPL use (including the possibility of proprietary derivative works) if they chose the MPL.[179] However, on January 3, 2012, Mozilla
Mozilla
released the GPL-compatible MPL 2.0,[182] and with the release of Firefox
Firefox
13 on June 5, 2012, Mozilla
Mozilla
used it to replace the tri-licensing scheme.[183] The crash reporting service was initially closed-source, but switched with version 3 from a program called Talkback to the open-source Breakpad
Breakpad
(and Socorro server). Trademark and logo[edit] See also: Mozilla Corporation
Mozilla Corporation
software rebranded by the Debian
Debian
project The name " Mozilla
Mozilla
Firefox" is a registered trademark; along with the official Firefox
Firefox
logo, it may only be used under certain terms and conditions. Anyone may redistribute the official binaries in unmodified form and use the Firefox
Firefox
name and branding for such distribution, but restrictions are placed on distributions which modify the underlying source code.[184] The name "Firefox" derives from a nickname of the red panda.[50] Mozilla
Mozilla
has placed the Firefox
Firefox
logo files under open-source licenses,[185][186] but its trademark guidelines do not allow displaying altered[187] or similar logos[188] in contexts where trademark law applies.

Logo used for Iceweasel

There has been some controversy over the Mozilla
Mozilla
Foundation's intentions in stopping certain open source distributions from using the "Firefox" trademark.[20] Open source browsers "enable greater choice and innovation in the market rather than aiming for mass-market domination."[189] Mozilla Foundation
Mozilla Foundation
Chairperson Mitchell Baker explained in an interview in 2007 that distributions could freely use the Firefox
Firefox
trademark if they did not modify source-code, and that the Mozilla
Mozilla
Foundation's only concern was with users getting a consistent experience when they used "Firefox".[190] To allow distributions of the code without using the official branding, the Firefox
Firefox
build system contains a "branding switch". This switch, often used for alphas ("Auroras") of future Firefox
Firefox
versions, allows the code to be compiled without the official logo and name, and can allow a derivative work unencumbered by restrictions on the Firefox
Firefox
trademark to be produced. In the unbranded build the trademarked logo and name are replaced with a freely distributable generic globe logo and the name of the release series from which the modified version was derived. Distributing modified versions of Firefox
Firefox
under the "Firefox" name required explicit approval from Mozilla
Mozilla
for the changes made to the underlying code, and required the use of all of the official branding. For example, it was not permissible to use the name "Firefox" without also using the official logo. When the Debian
Debian
project decided to stop using the official Firefox
Firefox
logo in 2006 (because Mozilla's copyright restrictions at the time were incompatible with Debian's guidelines), they were told by a representative of the Mozilla Foundation
Mozilla Foundation
that this was not acceptable, and were asked either to comply with the published trademark guidelines or cease using the "Firefox" name in their distribution.[191] Ultimately, Debian
Debian
switched to branding their modified version of Firefox
Firefox
"Iceweasel" (but in 2016 switched back to Firefox), along with other Mozilla
Mozilla
software. GNU IceCat
GNU IceCat
is another derived version of Firefox
Firefox
distributed by the GNU Project, which maintains its own separate branding.[192] Branding and visual identity[edit] Early Firebird and Phoenix releases of Firefox
Firefox
were considered to have reasonable visual designs, but fell short when compared to many other professional software packages. In October 2003, professional interface designer Steven Garrity wrote an article covering everything he considered to be wrong with Mozilla's visual identity.[193] Shortly afterwards, the Mozilla Foundation
Mozilla Foundation
invited Garrity to head up the new visual identity team. The release of Firefox
Firefox
0.8 in February 2004 saw the introduction of the new branding efforts. Included were new icon designs by silverorange, a group of web developers with a long-standing relationship with Mozilla. The final renderings are by Jon Hicks, who had worked on Camino.[194][195] The logo was later revised and updated, fixing several flaws found when it was enlarged.[196] The animal shown in the logo is a stylized fox, although "firefox" is usually a common name for the red panda. The panda, according to Hicks, "didn't really conjure up the right imagery" and was not widely known.[195] The Firefox
Firefox
icon is a trademark used to designate the official Mozilla build of the Firefox
Firefox
software and builds of official distribution partners.[197] For this reason software distributors who distribute modified versions of Firefox
Firefox
do not use the icon.

Promotion[edit]

Firefox
Firefox
was adopted rapidly, with 100 million downloads in its first year of availability.[200] This was followed by a series of aggressive marketing campaigns starting in 2004 with a series of events Blake Ross and Asa Dotzler called "marketing weeks".[201] Firefox
Firefox
continued to heavily market itself by releasing a marketing portal dubbed "Spread Firefox" (SFX) on September 12, 2004,[202] It debuted along with the Firefox
Firefox
Preview Release, creating a centralized space for the discussion of various marketing techniques. The release of their manifesto stated that “the Mozilla
Mozilla
project is a global community of people who believe that openness, innovation and opportunity are key to the continued health of the Internet.”[189] A two-page ad in the edition of December 16 of The New York Times, placed by Mozilla Foundation
Mozilla Foundation
in coordination with Spread Firefox, featured the names of the thousands of people worldwide who contributed to the Mozilla
Mozilla
Foundation's fundraising campaign to support the launch of the Firefox
Firefox
1.0 web browser.[203] SFX portal enhanced the "Get Firefox" button program, giving users "referrer points" as an incentive. The site lists the top 250 referrers. From time to time, the SFX team or SFX members launch marketing events organized at the Spread Firefox
Firefox
website. As a part of the Spread Firefox
Firefox
campaign, there was an attempt to break the world download record with the release of Firefox
Firefox
3.[204] This resulted in an official certified Guinness world record, with over eight million downloads.[205] In February 2011, Mozilla
Mozilla
announced that it would be retiring Spread Firefox
Firefox
(SFX). Three months later, in May 2011, Mozilla
Mozilla
officially closed Spread Firefox. Mozilla
Mozilla
wrote that "there are currently plans to create a new iteration of this website [Spread Firefox] at a later date."[206] In celebration of the third anniversary of the founding of the Mozilla Foundation, the "World Firefox
Firefox
Day" campaign was established on July 15, 2006,[207][208] and ran until September 15, 2006.[209] Participants registered themselves and a friend on the website for nomination to have their names displayed on the Firefox
Firefox
Friends Wall, a digital wall that will be displayed at the headquarters of the Mozilla
Mozilla
Foundation. The Firefox
Firefox
community has also engaged in the promotion of their web browser. In 2006, some of Firefox's contributors from Oregon State University made a crop circle of the Firefox
Firefox
logo in an oat field near Amity, Oregon, near the intersection of Lafayette Highway and Walnut Hill Road.[210] After Firefox
Firefox
reached 500 million downloads on February 21, 2008, the Firefox
Firefox
community celebrated by visiting Freerice
Freerice
to earn 500 million grains of rice.[211] Other initiatives include Live Chat, a service Mozilla
Mozilla
launched in 2007 that allowed users to seek technical support from volunteers.[212] The service was later retired.[213] In December 2017, Mozilla
Mozilla
collaborated with USA Network
USA Network
to create an alternate reality game promoting its television drama Mr. Robot; a component of this ARG was a Firefox
Firefox
extension known as "Looking Glass". The extension was pushed automatically to Firefox
Firefox
users in the United States via a system typically used for enabling "experiments" for user testing, but was disabled by default unless explicitly activated to participate in the ARG. Mozilla
Mozilla
received criticism from users and the media for automatically distributing an add-on without user consent, including the unclear source, purpose, and function of the extension (which carried the description "MY REALITY IS DIFFERENT THAN YOURS"), and that it was possible for Mozilla
Mozilla
to automatically install extensions into the browser. Mozilla
Mozilla
responded to the controversy, stating that the promotion was intended to be a "fun and unique" way for fans to engage with the series, but that the distribution practices "did not meet the standards to which we hold ourselves, causing concern that was surfaced through our Firefox community". The organization posted the extension to its add-ons repository, as well as a link to its source code, and stated that it would be re-evaluating its practices.[214][215][216] Performance[edit]

This section needs to be updated. Please update this article to reflect recent events or newly available information. (March 2018)

This section needs expansion with: It needs to take Firefox
Firefox
Quantum into account, which is being billed as "faster and lighter" than previous iterations.. You can help by adding to it. (March 2018)

In December 2005, Internet Week ran an article in which many readers reported high memory usage in Firefox
Firefox
1.5.[217] Mozilla
Mozilla
developers said that the higher memory use of Firefox
Firefox
1.5 was at least partially due to the new fast backwards-and-forwards (FastBack) feature.[218] Other known causes of memory problems were malfunctioning extensions such as Google
Google
Toolbar and some older versions of AdBlock,[219] or plug-ins, such as older versions of Adobe Acrobat Reader.[220] When PC Magazine in 2006 compared memory usage of Firefox
Firefox
2, Opera 9, and Internet Explorer
Internet Explorer
7, they found that Firefox
Firefox
used approximately as much memory as each of the other two browsers.[221] Softpedia
Softpedia
noted that Firefox
Firefox
1.5 took longer to start up than other browsers,[222] which was confirmed by further speed tests.[223] IE 6 launched more swiftly than Firefox
Firefox
1.5 on Windows
Windows
XP since many of its components were built into the OS and loaded during system startup. As a workaround for the issue, a preloader application was created that loaded components of Firefox
Firefox
on startup, similar to Internet Explorer.[224] A Windows
Windows
Vista feature called SuperFetch performs a similar task of preloading Firefox
Firefox
if it is used often enough. Tests performed by PC World
PC World
and Zimbra
Zimbra
in 2006 indicated that Firefox 2 used less memory than Internet Explorer
Internet Explorer
7.[225][226] Firefox
Firefox
3 used less memory than Internet Explorer
Internet Explorer
7, Opera 9.50 Beta, Safari 3.1 Beta, and Firefox
Firefox
2 in tests performed by Mozilla, CyberNet, and The Browser World.[227][228][229] In mid-2009, Betanews benchmarked Firefox
Firefox
3.5 and declared that it performed "nearly ten times better on XP than Microsoft
Microsoft
Internet Explorer
Internet Explorer
7".[230] In January 2010, Lifehacker compared the performance of Firefox
Firefox
3.5, Firefox
Firefox
3.6, Google Chrome
Google Chrome
4 (stable and Dev versions), Safari 4, and Opera (10.1 stable and 10.5 pre-alpha versions). Lifehacker timed how long browsers took to start and reach a page (both right after boot-up and after running at least once already), timed how long browsers took to load nine tabs at once, tested JavaScript
JavaScript
speeds using Mozilla's Dromaeo online suite (which implements Apple's SunSpider and Google's V8 tests) and measured memory usage using Windows
Windows
7's process manager. They concluded that Firefox
Firefox
3.5 and 3.6 were the fifth- and sixth-fastest browsers, respectively, on startup, 3.5 was third- and 3.6 was sixth-fastest to load nine tabs at once, 3.5 was sixth- and 3.6 was fifth-fastest on the JavaScript
JavaScript
tests. They also concluded that Firefox
Firefox
3.6 was the most efficient with memory usage followed by Firefox
Firefox
3.5.[231] In February 2012, Tom's Hardware
Tom's Hardware
performance tested Chrome 17, Firefox 10, Internet Explorer
Internet Explorer
9, Opera 11.61, and Safari 5.1.2 on Windows
Windows
7. Tom's Hardware
Tom's Hardware
summarized their tests into four categories: Performance, Efficiency, Reliability, and Conformance. In the performance category they tested HTML5, Java, JavaScript, DOM, CSS 3, Flash, Silverlight, and WebGL
WebGL
( WebGL
WebGL
2 is current as of version 51; and Java and Silverlight
Silverlight
stop working as of version 52)—they also tested start up time and page load time. The performance tests showed that Firefox
Firefox
was either "acceptable" or "strong" in most categories, winning three categories (HTML5, HTML5
HTML5
hardware acceleration, and Java) only finishing "weak" in CSS performance. In the efficiency tests, Tom's Hardware
Tom's Hardware
tested memory usage and management. In this category, it determined that Firefox
Firefox
was only "acceptable" at performing light memory usage, while it was "strong" at performing heavy memory usage. In the reliability category, Firefox
Firefox
performed a "strong" amount of proper page loads. In the final category, conformance, it was determined that Firefox
Firefox
had "strong" conformance for JavaScript
JavaScript
and HTML5. In conclusion, Tom's Hardware
Tom's Hardware
determined that Firefox
Firefox
was the best browser for Windows 7
Windows 7
OS, but that it only narrowly beat Google
Google
Chrome.[232] In June 2013, Tom's Hardware
Tom's Hardware
again performance tested Firefox
Firefox
22, Chrome 27, Opera 12, and Internet Explorer
Internet Explorer
10. They found that Firefox slightly edged out the other browsers in their "performance" index, which examined wait times, JavaScript
JavaScript
execution speed, HTML5/CSS3 rendering, and hardware acceleration performance. Firefox
Firefox
also scored the highest on the "non-performance" index, which measured memory efficiency, reliability, security, and standards conformance, finishing substantially ahead of Chrome, the runner-up. Tom's Hardware concluded by declaring Firefox
Firefox
the "sound" winner of the performance benchmarks.[233] In January 2014, a benchmark testing the memory usage of Firefox
Firefox
29, Google Chrome
Google Chrome
34, and Internet Explorer
Internet Explorer
11 indicated that Firefox
Firefox
used the least memory when a substantial number of tabs were open.[234] In benchmark testing in early 2015 on a "high-end" Windows
Windows
machine, comparing Microsoft
Microsoft
Edge, Internet Explorer, Firefox, Chrome, and Opera, Firefox
Firefox
achieved the highest score on three of the seven tests. Four different Javascript performance tests gave conflicting results. Firefox
Firefox
bested the others on the Peacekeeper benchmark, but was behind the Microsoft
Microsoft
products when tested with SunSpider. Measured with Mozilla's Kraken, it came second place to Chrome, while on Google's Octane challenge it took third behind Chrome and Opera. Firefox
Firefox
took the lead with WebXPRT, which runs several typical HTML5
HTML5
and Javascript tasks. Firefox, Chrome, and Opera all achieved the highest possible score on the Oort Online test, measuring WebGL
WebGL
rendering speed (WebGL 2 is now current). In terms of HTML5
HTML5
compatibility testing, Firefox was ranked in the middle of the group.[235] A similar set of benchmark tests in 2016 showed Firefox's Javascript performance on Kraken and the newer Jetstream tests trailing slightly behind all other tested browsers except Internet Explorer, which performed relatively poorly. On Octane, Firefox
Firefox
came ahead of IE and Safari, but again slightly behind the rest, including Vivaldi and Microsoft
Microsoft
Edge. Edge took overall first place on the Jetstream and Octane benchmarks.[236] Market adoption[edit] See also: Usage share of web browsers

Downloads have continued at an increasing rate since Firefox
Firefox
1.0 was released in November 2004, and as of 31 July 2009[update] Firefox
Firefox
had already been downloaded over one billion times.[237] This number does not include downloads using software updates or those from third-party websites.[238] They do not represent a user count, as one download may be installed on many machines, one person may download the software multiple times, or the software may be obtained from a third party. According to Mozilla, Firefox
Firefox
has more than 450 million users as of October 2012[update].[35][239] In July 2010, IBM
IBM
asked all employees (about 400,000) to use Firefox as their default browser.[240] Firefox
Firefox
was the second-most used web browser until November 2011, when Google Chrome
Google Chrome
surpassed it.[241] As of January 2018[update], Firefox
Firefox
was the second-most widely used desktop browser (and that position makes it the fourth-most popular with approximately 6% of worldwide usage share of web browsers across all platforms[242]).
