Enabling TraceMonkey in Firefox 3.1

TraceMonkey is the new Javascript Engine in Firefox 3.1 which is claimed to be 20-40 times faster than the order one. I have not tried out Firefox 3.1 myself yet and will wait for the official release.

Here's the steps to make sure TraceMonkey is enabled for both web content and XUL/chrome in Firefox 3.1:-

-Open a new tab and type "about:config"
-Enter "jit" in filter field
-Make sure both "javascript.options.jit.content" (for Web Content) and "javascript.options.jit.chrome" (for XUL/chrome) have the "true" value.
