Web Browser Grand Prix 4: Firefox 4 Goes Final

It's official! After four months of delays, twelve betas, and two RCs, Firefox 4 has gone final. But after all that, does this fox still have teeth? Can Internet Explorer 9 retain the WBGP title, or will it become the shortest-lived champion to date?

Performance Benchmarks: Java And Silverlight

GUIMark JAVA 5 Swing

Opera, Firefox, and Chrome make up the top three (respectively), all displaying about 41 frames per second. With 33.5 FPS, Safari takes fourth place, just a frame and a half per second ahead of IE9.

Encog Silverlight

Google Chrome still places first in Silverlight performance, followed closely by Microsoft's own IE9. Opera takes third place, with Firefox 4 just behind in fourth. In last place, Safari is noticeably behind the pack.

    Because people can't wait for half a second. I never had a single rendering problem with any of my browsers.

    Adblock Plus, Adblock Plus, Adblock Plus.

    That pretty much sums it up. No amount of optimization will help you when it comes to loading web pages if you have a large amount of adframes and such to slow you down.

    So have your super-fast IE9: I bet the ads will appreciate loading quick too.

    you must enjoy all those ads, in real world the difference in speed is negligible, but i sure has hell appreciate a rock stable browser, which is not what IE is, now saying that i have to say IE9 is definitely light years ahead of it's predecessor

    have used all 3 browser and found FF to be the most stable by far

    You must enjoy being an ignorant Fx fanboy. IE9 comes with adblocking features without needing any extensions.

    IE9 is indeed fast, but my question relates to Safari, a browser created specifically for Mac, not for Windows. On Mac Safari is incredible fast, why Tom’s did not tested Safari on the platform which it was designed for?

    Not if you use tracking protection.

If that's at the same time as Lion, then we might have to use the latest updated Snow Leopard for time reasons.

    This is why Firefox doesn't get 100:

  • I loaded up IE today because the Chase website gives me problems with Chrome, and I was surprised by how fast IE9 is now. Loading pages seemingly as fast or faster then chrome. I even thought of switching it to my primary browser, but the lack of Ad-block support killed it. It is a necessary feature and every browser should have it or something like it these days.

    The latest Chrome is indeed pretty fast, but I just can't live without Tab Mix Plus which is only available to Firefox. Someone please write a similar add-on for Chrome!!!
