On Monday, the Mozilla team announced the general availability of Firefox 3.1 beta 2 for testing. Aside from increased localization support, a new Private Browsing mode, new tab switching and preview behaviors, and support for a number of new web technologies (such as the W3C Geolocation API and offline applications), the new beta release uses the TraceMonkey JavaScript engine by default, and has made tweaks to the Gecko engine to speed content rendering.
