Firefox 4 Beta 7 is now available for public download - with remarkable performance boosts via "JägerMonkey" JavaScript compiler, added support for hardware-accelerated graphics, hardware acceleration on Windows XP and Mac OS X, and WebGL powered 3D capabilities without the need for additional plug-ins this release features lots of other improvements and bug-fixes.

I am using Firefox 4 Beta 5 and it's noticeably faster than Firefox 3.6, Mozilla is working hard to further enhance the browser performance and a new nightly developer build is now available for download with faster "JägerMonkey JavaScript Engine". The new javascript rendering engine is the code-name for the new JIT being developed for Mozilla's JavaScript engine where Jaeger means "hunter" in German.
