[Bug 16465] Re: Firefox eats way too many CPU cycles with certain pages
For me this page gives constant 50% CPU load and rising memory usage for Firefox 3 release version under Windows XP x64 SP2: http://www.theinquirer.net/gb/inquirer/news/2008/07/09/nvidia-g84-g86-bad I have dual-core CPU and Windows scheduler seems to be bouncing the thread around so that my whole system becomes unresponsible, not just Firefox. On some pages I have observed Firefox process eating 700+ MB of RAM (and increasing) when this high CPU load happens. If I lock the process to one of the cores, then the system responsiveness improves, but Firefox is still sluggish. When I check with Process Explorer, the IP of a thread consuming CPU time is inside js3250.dll address space or sometimes in xul.dll. When it is inside of js3250.dll stack trace also includes xul.dll. On one of the pages I have narrowed the problem down to the feedburner.com -- if I block *.feedburner.com using adblock, and reload the page the problem disappears. I believe it is a JavaScript related bug. -- Firefox eats way too many CPU cycles with certain pages https://bugs.launchpad.net/bugs/16465 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

i can confirm this bug on kubuntu 8.04. some websites causes firefox (either 2.0 or 3 beta) and xorg to use massive amount of CPU. (firefox CPU usage may go beyond 90% on these sites, and my box is Pentium D 3.2Ghz with 2 GB RAM). examples for these sites: http://www.ynet.co.il http://www.keshet-tv.com/nehederet/ -- Firefox eats way too many CPU cycles with certain pages https://bugs.launchpad.net/bugs/16465 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The webpage used in the original report has been fully redone since reporting, and is no longer publicly available. That's why you see it as working OK.
