We earlier told you about the new Firefox 3.1 and earlier this week Beta 3 became available for download. News include that the Beta is now available in 64 languages, updated Private Browsing Mode and a whole bunch of news for website designers like updated TraceMonkey JavaScript, native JSON support and other goodies. You can follow the link below to get to the official website for the beta, where you can find more information but also download and test what Mozilla has coming.
