Mozilla has announced the release of a new beta build for the long-time coming Firefox 4. Unlike the last couple beta releases which mostly just tweaked a few things here and there, this one actually brings along a couple of new features to get you excited. Most notably, it incorporates the JagerMonkey JIT compiler into the new SpiderMonkey engine, which will the browser a performance boost on script-heavy sites.
If youre already running a previous beta of Firefox 4 you should see an automatic update soon. Otherwise, if you would like to download beta 7 for Windows, Mac or Linux 32-bit 64-bit, just choose your operating system.
