User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/18.0 Firefox/18.0 Build ID: 20121119042013 Steps to reproduce: I tried to save all of my Facebook activity but Firefox crashed shortly before i scrolled to the end of the page. Restoring my 600 tab session, i wondered what would happen if one of them included an exploit that's been fixed in a more recent version of Aurora. Actual results: Crash, restore session. When i leave my Firefox (Aurora?) running for a week or more, if i've already checked its About screen, it would not have downloaded a more recent version even if i had checked it again shortly before the crash. Expected results: No crash, ask to update before restoring session to keep me and mine safe from malware.
