Firefox 3.6 Beta 1 is now available for download.

This first revision of the Beta of Firefox 3.6 / Gecko 1.9.2 introduces several new features:

  • 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  • Firefox 3.6 will alert users about out of date plugins to keep them safe.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.

Web developers and Add-on developers should read more detail about the many new features in Firefox 3.6 for developers on the Mozilla Developer Center. For the full list of changes since the alpha release, see this list.

Testers can download Firefox 3.6 Beta 1 builds for Windows, Mac OS X, and Linux in 53 different languages. Developers should also read the Firefox 3.6 for Developers article on the Mozilla Developer Center.

At this time most Add-ons have not yet been upgraded by their authors to be compatible with Firefox 3.6 Beta. If you wish to help test your Add-ons, please also download and install the Add-on Compatibility Reporter – your favorite Add-on author will appreciate it!
