[Bug 990991] [NEW] Firefox crashes randomly

[jsb]

Public bug reported:

Fresh install of 12.04

Firefox crashed randomly, usually with a few tabs open.
Usually the crash send me back to the login screen, but on some occasion the system freezes (alt-tab-F2 not working).
I am unable to pinpoint what is triggering the crash
