The most popular browser on Windows

Mozilla Firefox is a free and open source web browser descended from the Mozilla Application Suite, managed by the Mozilla Corporation. Firefox had 22.51% of the recorded usage share of web browsers as of July 2009, making it the second-most popular browser worldwide, after Internet Explorer.

In 5 months, Firefox has gathered steam and now owns more than 25% of usage share of web browsers closing the gap between it and IE.

To display web pages, Firefox uses the 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 add-ons created by third-party developers, the most popular of which include Adblock Plus, Video DownloadHelper, NoScript, Personas, FlashGot, and Greasemonkey, along with many others.

Firefox runs on various versions of Microsoft Windows (version 3.5 supports Windows Vista and XP; although not officially supported, Firefox is compatible with Windows 7 RTM), Mac OS X (10.4 or later officially supported), most Linux distributions, and many other Unix-like operating systems. Its current stable release branch is version 3.5, first released on June 30th, 2009. Firefox's source code is free software, released under a tri-license of GPL/LGPL/MPL.

    Yep, Firefox is one of the most used web browsers. Has lack of some features (but they can be added as extensions), sometimes it is a RAM-eater but still nice. Has a VERY customizable interface and its FREE!

    Firefox is still the most mature browser with extensions you can find. I like Chrome, specially in Windows, but never managed to live without extensions.
