User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9) Gecko/2008061015 Firefox/3.0 Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9) Gecko/2008061015 Firefox/3.0 Firefox 3 Freezes itself and the xserver with this w3c valid 60 lines of code when you scroll around. the rendering is extremely slow and needs full cpu capacity. Reproducible: Always Steps to Reproduce: 1. Just scroll up and down a few times Actual Results: The browser freezes and slows the xserver. cpu usage is at full capacity Expected Results: nothing of the above ^^ This HTML demonstrates a Firefox 3 performance bug in the gnome version of Firefox 3 (my current version is Build identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9) Gecko/2008061015 Firefox/3.0). Scrolling becomes very slow and freezes the browser and the xserver. The firefox process takes a whole cpu core. (Try scrolling up and down real fast) I noticed the bug in the Facebook application Armies, and extracted the important code. 3000+ lines of HTML & 10,000+ lines of CSS were shrunk down to about 60 lines of CSS+HTML. As a web developer i am a great supporter of Firefox and would love to see the Linux version as performant as the Windows and MacOS Version (both tested with this site).

I can't reproduce this with 3.0.10 or trunk. It could be a video driver issue.

This seems to be very similar if not identical to the bug that I just reported (585311). Except that in my case, at times, one does not even have to scroll, but if firefox and X do not crash immediately, then scrolling facebook pages will certainly cause a crash in both firefox and X, and CPU usage of 100%.

I can't reproduce this on Firefox 10 in Ubuntu 11.04. Please reopen if you're still seeing this problem.
