Firefox 4 is Still Slow, first test

Mozilla released the first beta of Firefox 4 yesterday. In addition to offering a spiffy, new interface and a whole host of new features, including enhanced HTML5 and WebM video support, the latest version should be faster. As there have been a few new browser releases recently, with Opera, Chrome and Safari all making great leaps forward, I though it was time to do a comprehensive head-to-head test to see how the new Firefox stacks up against them.


Rather than using my usual testing suite, WebKit’s SunSpider, for this shootout I used Mozilla’s Dromaeo testing suite. Dromaeo takes a lot longer to run — around 15 minutes or so — but it’s also much more comprehensive than SunSpider (it actually incorporates tests from Sunspider and also from Google’s V8 benchmark suite). For comparison, I also used the Peacekeeper tests, another comprehensive browser performance testing suite. Testing was done on my 2.53 GHz Intel Core 2 Duo MacBook Pro; only the major Mac browsers were tested.

If you’d like to try Firefox 4, you can download it here. As with all pre-release software, there may still be some gremlins to iron out.
