The most popular browser on Windows

Share

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.

    I'm not quite sure why Firefox has caught on as well as it has vs. superior browsers such as Opera and Safari. Both performance and feature set are inferior to Opera. That said, Firefox tends to be compatible with a lot of "quirky" sites that Opera chokes on. Also, Firefox has the best in-page search functionality of all current browsers.

    I use a lot of other browsers (don't ask why).
    Compared to FireFox, they all suck.
    Not just because of the add-ons. Just because FireFox is king.

    There's a whole bunch of addons for Firefox, but not all of them are useful or work properly.. This can of course be because most of them are third party generated, but Firefox itself is complete enough for most people to get by without having to download any addons.

    Sometimes a bit more sluggish than that of Safari and Chrome, although bearing a much larger burden in the form of add-ons and customization. Definitely one of the best browsers available.
