While Microsoft is closing in on the final release of Internet Explorer 7, Mozilla has made available for download starting today the release Candidate 3 build of its Firefox 2.0. "Firefox 2 Release Candidate 3 (RC 3) is a preview release of our next generation Firefox browser and is being made available for download to Web application developers, our testing community and users who want to get a sneak peek at the next version of Firefox. Please note that at this time, users should not expect all of their extensions, plugins and themes from previous versions of Firefox to work properly," reads a Mozilla's presentation message.

Firefox 2.0 Release Candidate 3 can be downloaded via this link. The browser offers support for a number of 39 languages and Mozilla is releasing RC3 for Windows, Mac OS X and Linux i686.

Mozilla called the release a development milestone and has enumerated a few aspects of the browser that were overhauled: Visual Refresh, built-in phishing protection, enhanced search capabilities, improved tabbed browsing, resuming your browsing session, previewing and subscribing to Web feeds, inline spell checking, Live Titles, improved Add-ons manager, JavaScript 1.7, extended search plugin format, updates to the extension system, client-side session and persistent storage, SVG text and new Windows installer.
