Firefox 3.1 Beta 3 Released
 

Mozilla has released the third beta for Firefox 3.1 (which may become Firefox 3.5). This beta includes the new location bar, Mozilla's new JavaScript engine Tracemonkey, new HTML5 features and many other enhancements. It looks the same on the surface, but there are many changes under the hood.
