We are on the road to Firefox 3.1 Beta 1, so there is plenty to test! If you want to test your favorite Firefox Feature, great! But you can also run some more tests in Litmus and try out the Nightly Build and the other great new Firefox improvements,” revealed Mozilla's Carsten Book.
In addition to performance boost, Firefox 3.1 will also feature Private Browsing Mode, which Microsoft introduced in Internet Explorer 8 Beta 2, support for Windows Vista's Aero Glass, but also closer integration with Ogg Vorbis and Theora codecs, native JSON, CSS 3 and HTML 5. Following the release of Firefox 3.1 Beta 1 in October, Mozilla will make available at least one more beta in November 2008.
If you already have Firefox 3 or Firefox 2, you will receive an automated update notification within 24 to 48 hours. This update can also be applied manually by selecting 'Check for Updates…' from the Help menu,” said Mike Beltzner, Mozilla's User Experience lead.
