Early adopters can now download Firefox 4.0 pre-Beta preview nightly Builds and start test diving JägerMonkey.
Still, users need to keep in mind that the releases are very early versions of Firefox 4.0 Beta 6, designed for testing and not for deployment into production environments.

“JägerMonkey is our new optimizing JIT compiler for JavaScript. It sits underneath our existing JIT, TraceMonkey, which appeared in Firefox 3.5,” revealed Mozilla’s
David Anderson.
“JägerMonkey is a general-purpose compiler which converts entire methods to machine code. The goal is to get great baseline performance.
