Firefox 3

The Web is all about innovation, and Firefox 3 sets the pace with dozens of new features, including the smart location bar, one-click bookmarking and blindingly fast performance.

Mozilla Firefox (abbreviated officially as Fx, but also commonly as FF) is a free web browser descended from the Mozilla Application Suite, managed by the Mozilla Corporation. Firefox had 19.03% of the recorded usage share of web browsers as of June 2008, making it the second-most popular browser in current use worldwide, after Internet Explorer.

Firefox uses the free Gecko layout engine, which implements some current web standards plus a few features which are intended to anticipate likely additions to the standards.

Firefox includes tabbed browsing, a spell checker, incremental find, live bookmarking, a download manager, and an integrated search system that uses the user's desired search engine. Functions can be added through around 2,000 add-ons created by third-party developers,the most popular of which include NoScript (script blocker), Tab Mix Plus (adds many customizable options to tabs), FoxyTunes (controls music players), Adblock Plus (ad blocker), StumbleUpon (website discovery), DownThemAll! (download functions) and Web Developer (web tools).

Firefox runs on various versions of Microsoft Windows, Mac OS X, Linux, and many other Unix-like operating systems. Its current stable release is version 3.0, released on June 17, 2008.Firefox's source code is free software, released under a tri-license GPL/LGPL/MPL.
