Firefox 3 Performance Issue on Linux

Internet, Linux , , , , , Add Comment (3)


I created a HTML that shows a low performance issue in Firefox 3 on Linux. It is simmilar to this Launchpad Bug.
This HTML was extracted from the Facebook app Armies,it originally had 3000+ lines of HTML & 10,000+ lines of CSS and i shruk it to about 60 lines of code. 60 line of bad code (but w3c valid).

See for yourself: http://lubosz.de/Firefox3PerformanceBug/

I also posted it on bugzilla.mozilla.org

I made a screen recording of my firefox going nuts (comparded to Konqueror KDE4 and Opera 9.50):

    Hello, I’d like to say that it isn’t a “Linux-only” bug. I just reproduced it on a Windows XP machine (ATI HD 3200 video card). Under Vista, on the same machine, Firefox works just fine. Interesting, isn’t it?

    Why would you make a website like what you are demonstrating?
