Mozilla Firefox 4 Beta 3

Mozilla Firefox 4 beta 3 just got released. Mozilla is beginning to make more progress with its new JavaScript engine JaegerMonkey, which is now about 10% faster than the TraceMonkey engine that is integrated in Firefox today.

If we believe Mozilla’s latest crash report data, it may be the most stable Firefox 4 Beta to date. In fact, the data indicates that the browser is just as stable as the current 3.6.8. The fourth beta is already available as a nightly build and we noticed that Mozilla is making slow, but consistent progress to improve the performance of its new JavaScript engine. JaegerMonkey is now indicated to achieve a Sunspider performance of 596.2 ms, which is the first time Mozilla has broken the 600 ms mark. TraceMonkey is at 653.9 ms.

Mozilla still plans on releasing JaegerMonkey in September and it appears that the team has still quite a bit of work to do to take the engine below the stated goal of somewhere between 400 and 500 ms. In V8, JaegerMonkey comes in at 5916.4 ms vs. TraceMonkey’s 6623.4 ms. Google’s Chrome stands at 1670 ms, according to Mozilla.
