Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

It is happening with 12.04 (just upgraded my system):

when firefox is open the system may shutdown spontaneously. All jobs stop working, the opening screen appears asking the password as if the machine was just rebooted.

After re-opening and restarting firefox the message says Firefox is having problems to recover tabs possibly due to one of the open webpages.

Any clue ?
