Replicated with fresh (but upgraded to current state) 32 and 64 lucid instances - on both VMs firefox was started in safe-mode.
As per the apport wiki https://wiki.ubuntu.com/Apport/: I executed `sudo service apport start force_start=1' prior to firefox launch. However apport was not started, so I *cannot* provide the information that is required to submit a valid bug. Nor is it possible to examine about:memory as firefox is not longer with us. The best I can do is collect apport information on one of the VM instances - bug 1019094. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1018263 Title: exhaustive memory leak Status in “firefox” package in Ubuntu: Invalid Bug description: If I leave firefox running over night, since upgrading to 13.0.1 Firefox, firefox exhausts all system memory, running with 100% load on one core. This has been noticed on other platforms by other users (for example here http://support.mozilla.org/en-US/questions/930472). Action: Leave firefox running and go home from work. Expect: Low load and low memory use from firefox when get back in the morning. See: 100% load on one core due to ff, and full memory (in this case 12GB) exhaustion (or worse OOM killer marks on other long running applications, including but not limited to compiz). Extra points: I have small multiples of tabs open, but nothing actually doing anything and not that had caused any problems prior to this version. It seems ff13.0.1 could give NT a run for it's money if it were in the airlines stakes ;| $ lsb_release -rd Description: Ubuntu 10.04.4 LTS Release: 10.04 $ dpkg -l | grep firefox ii firefox 13.0.1+build1-0ubuntu0.10.04.1 Safe and easy web browser from Mozilla ii firefox-3.0 13.0.1+build1-0ubuntu0.10.04.1 Safe and easy web browser from Mozilla - transitional package ii firefox-3.0-branding 3.6.10+build1+nobinonly-0ubuntu0.9.10.1 dummy upgrade package for firefox-3.0 -> firefox-3.5 ii firefox-3.0-gnome-support 13.0.1+build1-0ubuntu0.10.04.1 Safe and easy web browser from Mozilla - transitional package ii firefox-branding 13.0.1+build1-0ubuntu0.10.04.1 Safe and easy web browser from Mozilla - transitional package ii firefox-gnome-support 13.0.1+build1-0ubuntu0.10.04.1 Safe and easy web browser from Mozilla - GNOME support $ uname -srvm Linux 2.6.32-41-generic #90-Ubuntu SMP Tue May 22 11:29:51 UTC 2012 x86_64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1018263/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
