Reproducible: Always Steps to Reproduce: 1.have around 5 tabs open 2.upload pics, download pics, post here and there, have your webmails open 3.open and close tabs according to your browser needs Actual Results: after a couple of hours, Firefox becomes slower, every page you open take a long time to load, only if you move your mouse it opens right away Expected Results: it should have been stable and open everything right away instead of when i move my mouse
Does the issue occur in Safe Mode? http://support.mozilla.com/en-US/kb/Safe%20Mode How about with a new profile? http://support.mozilla.com/en-US/kb/Basic%20Troubleshooting#w_8-make-a-new-profile
Version: unspecified → 4.0 Branch
This happens also in safe mode, new profile doesn't seem to make any difference
Please post the contents from about:memory next time you experience the slowness.
Mark -> Any update? Were you able to get the contents from about:memory?

Tim -> Any update on this ? It seems that more and more people experience this problem, shutting down add-ons or plugins or safe mode doesn't seem to help, update the video card drivers is not helping. I am experiencing it right now, but i am still confused what's causing it.

A very loosely related BR where moving the Mouse affects the Browser is demonstrated in Bug 661717 it is accompanied by low Memory.
Created attachment 542751 [details] about:config file I am currently using Firefox 5.0 and this problem started when i uploaded some mp3's and m4a's with 2 different webmail accounts...so it might has something to do with this. Also i found out that the browser loads when i press buttons on my keyboard, but when i do not touch them it stops loading. Here is a quick movie that i made that shows the problem. http://www.dwmusicstore.com/mark/firefox.wmv
Mark -> Are you still having issues with Firefox 11?
Tim -> no i haven't had the problem for quite awhile, so i think it is has been fixed...
Thanks for the update Mark!
