Firefox 4 becoming slow after few hours of use
User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:2.2a1pre) Gecko/20110330 Firefox/4.2a1pre Build Identifier: Mozilla/5.0 (Windows NT 6.1; rv:2.2a1pre) Gecko/20110330 Firefox/4.2a1pre Firefox becomes very slow after 2 hours of work, loading pages come to a near halt and only continues after you move your mouse. 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?
It is so slow now, i cannot press anything, so i am posting this with IE9 :-( Memory Usage Overview Memory mapped: 166,723,584 Memory in use: 139,318,218 Other Information Description Value malloc/allocated 139,321,266 malloc/mapped 166,723,584 malloc/committed 148,361,216 malloc/dirty 2,711,552 win32/privatebytes 189,366,272 win32/workingset 211,521,536 js/gc-heap 32,505,856 js/string-data 6,702,468 js/mjit-code 8,501,512 storage/sqlite/pagecache 4,132,208 storage/sqlite/other 956,544 gfx/d2d/surfacecache 0 gfx/d2d/surfacevram 0 gfx/surface/win32 17,165,726 images/chrome/used/raw 0 images/chrome/used/uncompressed 162,296 images/chrome/unused/raw 0 images/chrome/unused/uncompressed 0 images/content/used/raw 1,624,118 images/content/used/uncompressed 16,108,006 images/content/unused/raw 24,177 images/content/unused/uncompressed 195,969 layout/all 5,109,989 layout/bidi 886 gfx/surface/image 5,520 shmem/allocated 806,912 shmem/mapped 806,912 content/canvas/2d_pixel_bytes 707,820
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.
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!
