History

Firefox OS was publicly demonstrated in February 2012, on Android-compatible smartphones. By December 16, 2014, fourteen operators in 28 countries throughout the world offered Firefox OS phones. On December 8, 2015, Mozilla announced that it would stop sales of Firefox OS smartphones through carriers. Mozilla later announced that Firefox OS smartphones would be discontinued by May 2016, as the development of "Firefox OS for smartphones" would cease after the release of version 2.6. Around the same time, it was reported that Acadine Technologies, a startup founded by

In January 2016, Mozilla announced that Firefox OS would power Panasonic's UHD TVs (as previously announced Firefox OS "would pivot to connected devices"). In September 2016, Mozilla announced that work on Firefox OS had ceased, and that all B2G-related code would be removed from mozilla-central.

Project inception and roll-out

Commencement of project

On July 25, 2011, Andreas Gal, Director of Research at

, announced the "Boot to

" Project (B2G) on the mozilla.dev.platform mailing list. The project proposal was to "pursue the goal of building a complete, standalone operating system for the open web" in order to "find the gaps that keep web developers from being able to build apps that are in every way the equals of native apps built for the iPhone, Android, and Windows Phone 7." The announcement identified these work areas: new

, "Mozilla says that B2G is motivated by a desire to demonstrate that the standards-based open Web has the potential to be a competitive alternative to the existing single-vendor application development stacks offered by the dominant mobile operating systems." In 2012, Andreas Gal expanded on Mozilla's aims. He characterized the current set of mobile operating systems as " walled gardens" and presented Firefox OS as more accessible: "We use completely open standards and there’s no proprietary software or technology involved." (That changed in 2014; see Digital rights management (DRM), below.) Gal also said that because the software stack is entirely HTML5, there are already a large number of established developers. This assumption is employed in Mozilla's WebAPI. These are intended W3C standards that attempt to bridge the capability gap that currently exists between native frameworks and web applications. The goal of these efforts is to enable developers to build applications using WebAPI which would then run in any standards compliant browser without the need to rewrite their application for each platform.

Development history

In July 2012, Boot to Gecko was rebranded as 'Firefox OS', after Mozilla's well-known desktop browser,

, and screenshots began appearing in August 2012. In September 2012, analysts Strategy Analysts forecast that Firefox OS would account for 1% of the global smartphone market in 2013, its first year of commercial availability. In February 2013, Mozilla announced plans for its global commercial roll-out of Firefox OS. Mozilla announced at a press conference before the start of

In 2014, Gal announced a change in course, writing that future versions of the Firefox browser would include DRM. Implementation of DRM in the Firefox browser began with version 38. In August 2015, attempts by Matchstick TV (based on Firefox OS) to add DRM caused the demise of Matchstick, a decision that

B2G OS was forked from Firefox OS following Mozilla's decision to discontinue support for their mobile operating system. The decision was made, according to Ari Jaaksi and David Bryant, in order to "evolve quickly and enable substantial new architectural changes in Gecko, Mozilla’s Platform Engineering organization needs to remove all B2G-related code from mozilla-central." , B2G OS is no longer maintained.

Comparison with Android

Firefox OS used the Linux kernel like Android does. Firefox OS used the Gecko engine on top of the Linux kernel to render the screen output. Apps were written using HTML5, CSS, and JavaScript—all three being cooperative languages used in making internet webpages. In essence, apps on Firefox OS were web apps and the OS could be thought of as a Web browser that stored content off-line. On the other hand, Android's apps are coded in Java using Android Studio. Android also enjoys greater maturity and support. Despite these differences, Firefox OS did feature all the essentials required to use a smartphone. Firefox launched its first official device in Germany in 2014, which was an Alcatel One Touch Fire. The device had a 3.5” HVGA screen, Cortex A5 processor, 256MB RAM, and 512MB storage. , Mozilla had launched 12 smartphones across 24 countries.

said that Firefox OS has the advantage that users need not install an app to use it. Mozilla sought to make the most of this with the search functionality built into Firefox OS, a core feature of the platform. Janne Lindqvist, a mobile security researcher at the Rutgers University WINLAB, expressed concern about the discovery mechanism of a Web-based platform, but a Mozilla spokesperson stated that Mozilla required developers to "package downloadable apps in a zip file that has been cryptographically signed by the store from which it originated, assuring that it has been reviewed." In addition, "apps coming back from search are given only limited access to device programming interfaces and applications, unless the user grants permission for further access."

Devices

Officially and unofficially supported devices

The structural similarities between Firefox OS and Android allow the Mozilla platform to run on a number of devices that ship with Android. While some ports of Firefox OS are hardly different from their original versions, others are heavily modified to fit the device in question. There are quite a few to note that are specifically made for Firefox OS as stated above. There are some that are designed for the developers themselves and others that are consumer-phones. There are also emulators for testing both apps and the OS itself on the desktop which are designed for both OS testing and the developers themselves.
