Be sure to check out Brendan’s Roadmap Updates for more.  Also here are a few handy links from John Resig on the testing:

So the big question is, will Firefox be able to make Firefox 3.1 even faster in the area of JavaScript?  If you have the nightly build of Firefox 3.1 installed, you can turn TraceMonkey on by going to about:config and then toggle the javascript.options.jit.content setting from false to true.  For the rest of us out there though, this is just one more surprise to look forward to once Firefox 3.1 gets rolled out to the public.
