Steve Langasek, thank you for the clarification. Could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.13-rc6 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results.

I just upgraded to ringtail (from pangolin, not quetzal) and I'm seeing frequent firefox hard freezes, where I have to kill the process. (It is killable, though.) It's not related to youtube or flash; most often it happens when I'm visiting a new page. The problem isn't part of Ubuntu's firefox build, because I'm using Firefox 20.0 from mozilla.org.

This bug can be reproduced on a system without the Adobe Flash plugin installed by using Firefox to watch a YouTube video or some other online video. It will crash fairly soon due to bug #1085342. The likelyhood of crashing is possibly higher if using Firefox 18.0.1 due to JavaScript related stability issues which are fixed in Firefox 18.0.2.
