Firefox 9 Released, JavaScript Performance Greatly Improved

MrSeb writes "Firefox 9 is now available — but unlike its previous rapid release forebears where not a lot changed, a huge feature has landed with the new version: the JavaScript engine now has type inference enabled. This simple switch has resulted in a 20-30% JS execution speed increase (PDF), putting JaegerMonkey back in line with Chrome's V8 engine, and even pulling ahead in some cases. If you switched away from Firefox to IE or Chrome for improved JS performance, now is probably the time to give Firefox another shot."

Re:Just because of speed?

So true. I switched to Chrome at the weekend for exactly this reason. I can't remember when JS or render speed were an issue for me, but useability just keeps going down with FF.

Let's stop with the posts anouncing the latest release and wake me up when the Firefox devs are listening to their users once more.

Sure, then leave it open overnight. Firefox leaks like a sieve.
