Public bug reported: 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.
