Firefox Beta 3.6 (revision 3) now available for download

Editor’s note: Mozilla released Firefox 3.6 beta 3 on Tuesday, November 17, 2009. Check out the Mozilla Developer News announcement reposted below for more details.

Last night the Mozilla community released Firefox 3.6 Beta 3, making it available for free download and issuing an update for all Firefox 3.6 beta users. This update contains over 80 fixes from the last Firefox 3.6 beta, containing many improvements for web developers, Add-on developers, and users. More than half of the thousands of Firefox Add-ons have now been upgraded by their authors to be compatible with Firefox 3.6 Beta. If your favorite Add-on isn’t yet compatible, you can also download and install the Add-on Compatibility Reporter – your favorite Add-on author will appreciate it!

The Mozilla community appreciates your feedback and assistance in testing this preview of the next version of Firefox. Your beta software will update itself periodically, and eventually will be updated to the final release itself.

The Beta of Firefox 3.6 / Gecko 1.9.2 introduces several new features for users to evaluate:

• (New in this update) A change to how third-party software integrates with Firefox to increase stability.
• (New in this update) The ability to run scripts asynchronously to speed up page load times.
• A mechanism to prevent incompatible software from crashing Firefox.
• Users can now change their browser’s appearance with a single click, with built in support for Personas.
• Firefox 3.6 will alert users about out of date plugins to keep them safe.
• Open, native video can now be displayed full screen, and supports poster frames.
• Support for the WOFF font format.
• Improved JavaScript performance, overall browser responsiveness and startup time.
• Support for new CSS, DOM and HTML5 web technologies.
