Title: Extremely slow Ajax/Javascript/CSS performance in Firefox 3 using non- free nvidia-glx-new Status in Mozilla Firefox: Invalid Status in firefox package in Ubuntu: Confirmed Status in linux-restricted-modules-2.6.24 package in Ubuntu: Won't Fix Bug description: Binary package hint: firefox-3.0 With Ubuntu 8.04 Firefox 3.0 has extremely slow Ajax/Javascript performance (I'm not sure exactly what). Probably CSS related. #1 Gmail scrolls very slowly (compare this by switching gmail to HTML version at the bottom of inbox) #2 Javascript images open/close/transition extremely slow examples: http://www.shacknews.com/ (images near the top of page, when transitioning, bring FF3.0 to its knees) http://www.worldofwarcraft.com/downloads/ssotd/#latest (images opening and switching to next one) http://www.transmissionbt.com/screenshots.php (opening and closing images are very choppy) There are many more, those are just a few. I have both enabled and disabled Compiz but the problem is still there. I am not a web developer and can't pinpoint exactly what sort of code is causing the extreme slowness but I have tested it on multiple machines to make sure. I have compared it to my Windows XP dual boot box and the difference is night and day so it is definitely a Linux issue. Also on a Mac OS 10.4 machine its noticeably faster. This bug: https://bugs.launchpad.net/bugs/217580 Is similar but only deals with Gmail, it is now known to be widespread issue. With performance this slow Firefox 3.0 beta should never have been the default browser. Unless its just the few machines I've used of course.
