Storage

Each browser has a built-in tool for managing the list of bookmarks. The list storage method varies, depending on the browser, its version, and the operating system on which it runs. Netscape-derived browsers store bookmarks in the single HTML-coded file ''bookmarks.html''. This approach permits publication and printing of a categorized and indented catalog, and works across platforms. Bookmark names need not be unique. Editing this file outside its native browser requires editing HTML. Firefox 3 stores bookmarks, history, cookies, and preferences in a transactionally secure database format (

''. Bookmarklets are possible because the JavaScript URI scheme allows JavaScript programs to be stored as URIs, which can be stored in bookmarks. Bookmarklets have access to the current page, which they may inspect and change. As such, they can be simple "one-click" tools which add functionality to the browser. Bookmarklets are typically installed by navigating to a web page that links to a JavaScript URI, right-clicking the link, and clicking the bookmark option.
