If you love Firefox and are willing to serve as Mozilla's guinea pig, the foundation in charge of Firefox's development today announced the availability of Firefox 3.1 beta 2. The new version of the browser includes a lot of new functionality, focused primarily on feature addition and newer Internet technologies like W3C Geolocation, the TraceMonkey Javascript Engine, private browsing and more. The inclusion of private browsing is an important concern to people using the browser on public computers, and new support such as things like video and audio web elements.
You can download the software from Mozilla's site, where you can get a beta build for the three big platforms Firefox supports. As always, try beta software at your own risk, though I wouldn't worry too much about installing this one, plus you get athe chance to help Mozilla out.
