** Description changed: When switching apps (with alt-tab, or clicking the Launcher) *to* Firefox, Firefox crashes. This does not occur for a while after reboot. However, once the first crash has happened, a restarted Firefox will reliably continue to crash every time it is switched *to*. So, starting Firefox works; restoring the previous session works; navigating around, choosing different tabs, adding new tabs works. Switching away from Firefox works. However, switching back to Firefox causes it to crash every time. A reboot cures the problem (until it starts again). Crash report sent to Mozilla (about a zillion times) and should be therefore attached to this bug by apport, but if not: https://crash- stats.mozilla.com/report/index/bp-dbbaef36-287e-4e2b-85bd-4ef8e2120810 Disabling Firebug seems to have cured the problem. - ProblemType: Bug - DistroRelease: Ubuntu 12.04 + [SRU justification] + Looking through Mozilla's crash database, we're currently responsible for about 1500 crash reports per week (taking in to account the different variations of this trace), second only to Flash + + See some comments from our very unhappy users - + + https://crash-stats.mozilla.com/report/index/03c68f08-14ed-42ab-bb12-db4212120811 : + "browser keeps crashing as soon as i run it. cant do anything" + + https://crash-stats.mozilla.com/report/index/fc95cd37-cdc9-458b-b373-d6a2d2120815 : + "Firefox keeps crashing everytime I open it, unless I open in safe mode." + + https://crash-stats.mozilla.com/report/index/010be177-7e91-446d-b823-845442120813 : + "Just starting gives me a crash" + + https://crash- + stats.mozilla.com/report/index/3b04c9ab-0884-4205-a301-ca4132120811 : + "Again I just start Firefox and it does not stay for one second, before + he kill himself..." + + https://crash-stats.mozilla.com/report/index/c8ee0432-befe-427e-bdad-c67b62120811 : + "This happened at startup.
