Firefox 3 Performance Issue on Linux

Internet, Linux , , , , , Add Comment (7)


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?

    Hi. I wanted to drop you a quick note in order to convey my personal thank you. I have been recently following your web log for a month or so and have picked up a lot of good information and facts as well as loved the way you have organised your site. I am trying to run my very own webpage but I think it’s too standard and I want to concentrate more on more compact issues. Being all things to all people is not all that its cracked up to be.

    Have you considered adding several social bookmarking buttons to these sites. At the very least for facebook.

    Fantastic blog! Do you have any hints for aspiring writers? I’m planning to start my own blog soon but I’m a little lost on everything. Would you propose starting with a free platform like Wordpress or go for a paid option? There are so many choices out there that I’m totally overwhelmed .. Any tips? Thanks!
