Only 4 months after releaasing Firefox 3, Firefox 3.1 beta 1 was released yesterday (Oct 14th, 2008) at 2:42 pm PT.
The Firefox 3.1 Beta 1 milestone is focused on testing the core functionality provided by many new features and changes to the platform scheduled for Firefox 3.1. Ongoing planning for Firefox 3.1 can be followed at the Firefox 3.1 Planning Center, as well as in mozilla.dev.planning and on irc.mozilla.org in #shiretoko.

New features and changes in this milestone that require feedback include:

  • Web standards improvements in the Gecko layout engine
  • Added support for CSS 2.1 and CSS 3 properties
  • A new tab-switching shortcut that shows previews of the tab you’re switching to
  • Improved control over the Smart Location Bar using special characters to restrict your search
  • Support for new web technologies such as the <video> and <audio> elements, the W3C Geolocation API, JavaScript query selectors, web worker threads, SVG transforms and offline applications.

More information about new web developer features are available in the Web Tech blog post.

NB: Firefox 3.1 Beta 1 is available in over 35 languages as a public preview release intended for developer testing and community feedback.
