Mozilla & Gecko clones The Firefox guys at Mozilla have released the 2nd beta for Firefox 3.1. "The public beta of Mozilla's first Web browser to incorporate a private browsing mode, is being made available to the general public today, although as before, the organization has yet to make it official." This build also includes the new TraceMonkey JavaScript engine, and for web content, it's enabled by default. If you want to enable it for XUL/chrome as well, go to about:config, search for 'jit' and set the XUL/chrome option to 'true'.

Javascript + DOM getting slower

I was pretty excited about the new tracemonkey javascript engine when it was first announced. It looked to be a big improvement in the synthetic benchmarks they showed. And a big step in catching up to Google Chrome in speed.

But testing Firefox 3.1 Beta 2 with the jsBalls fight timedemo ( ) it seems slower than Firefox 3. Safari 3.2 and Opera 10 alpha 1 both were much faster than their predecessors in this benchmark, I was hoping Firefox would keep pace.

I'm not seeing any speed increase at all, in fact it's much slower than v3.0. Am I missing something?

I tried this site: to test both and 3.1 just choked?

Sorry if I worded my message funny. I was complaining about it getting slower. So yes, no speed increase at all. Just a marginal decrease.

That site is really cool. People are doing some really neat things with javascript.
