Bug Description

Binary package hint: firefox

- Config : Core2Duo T7500 / 2GB RAM / nVidia 8400M GS
- Program concerned : Firefox
- Possible cause : nvidia GPU
- Symptoms : Firefox is anormally slow, especially when changing tabs or using javascript onmousemove scripts. Wastes a lot of CPU and RAM. Makes Firefox mostly unuseable... Same for Opera and GrandParadiso (Firefox 3).

I can confirm this. It happened with me after the latest firefox2 update. 'Top' shows that firefox-bin consumes 90 plus % of CPU resources. This is on a 1.8Ghz Pentium4 with 768Mb memory also with an nvidia GPU.

I just recently started having the same problem. I'm using a similar setup to the original poster

Core2Duo / 3 GB RAM / nVidia 8600GT
Firefox 2.0.12
Kubuntu 3.5 with all updates

Firefox has worked fine for a couple months and then something occurred recently. Not sure exactly when but perhaps within the last 4 days. There was an update for my kubuntu system during that time. I forgot what libraries were updated. Could be the cause. I don't remember the problem right after the 2.0.12 update but I could be wrong.

Firefox is very slow especially during tab switches... about 1--2 seconds to switch.. Very annoying.

Whoa. I just saw But 144216 "Slow switching tab in firefox/opera when the desktop effects are enabled in Gutsy Gibbon".... this is definitely my problem. I've been using Emerald instead of kde-window-decorator... when I switch to kde-window-decorator it works fine again...

Other reporters, are you using Emerald? This could be a dupe.

I agree with jasonq above.. this is probably a duplicate of 144216, and is most likely a bug with emerald, not firefox.

I can confirm that. It only affects the linux (Ubuntu 7.10 Gusty) version of firefox2. Firefox 3 gets even worse - onmousover scripts often crash. Same firefox version in windows works fine - no lag with onmouseover scripts. With Opera-linux they work perfectly - no problems at all. And I do not use any desktop effects.

Sorry but Firefox-2 is getting near EOS and they wont be fixing anything but major issues security issues mainly. Please try to reproduce this with Firefox-3.0 if you can reproduce this bug please click on Help > Report a problem and file the bug that way. This does not mean that it wasn't already fixed.

Changed in firefox:
status: New → Won't Fix

I can confirm this happens to me with 8.04.1 and Firefox 3.0.3.
I am not running desktop effects, but I am running Xinerama with (4) monitors.
I am using the Envy manager for my nVidia 8800GT card.
