Mozilla has finally signed off Firefox 4 as a Release Candidate for Windows, Mac and Linux and is now available as a release candidate in more than 70 languages.
Firefox 4, based on the Gecko 2.0 engine, brings an updated user interface, new ways to organize tabs, a revamped add-on manager, support for HTML5 video standards, multitouch support on Windows 7 and a range of performance and security enhancements.
Mozilla encouraged testers to put the browser through its paces by visiting the Web O' Wonder which features cutting-edge demos targeted for Firefox 4. Developers are also invited to submit their own demos to the Mozilla Developer Network Demo Studio.
As far as the Firefox 4 development team are concerned, this's expected to be the final, release-ready build of Firefox 4; Mike Beltzner, Mozilla's Director of Firefox, says that this RC "represents the code we intend to ship as Firefox 4."
There're no significant changes between beta 12 and the RC. About 8000 bugs have been squashed, and it looks like plug-ins are finally up to release-level stability.
The millions of users testing Firefox 4 will be automatically updated to this version and will join our Mozilla QA team in validating the new features, enhanced performance and stability and HTML5 capabilities in Firefox 4.
