All the rage seems to be who has the fastest JavaScript engine these days. Chrome has it's V8 engine, Firefox with their TraceMonkey, and there is also the WebKit project. What I wanted to do was get some hard data to compare all these engines along with older browsers.

Firefox has just released it's newest beta. In this beta is their new javascript engine called TraceMonkey which is, however, disabled by default. It's easy to enable though by toggling a simple option in about:config. Look for "javascript.options.jit.content" and set it to true.
