"Restore Previous Session" isn't working.

Posted

I just re-opened Firefox after closing it with several dozen tabs open, and it made no apparent effort to bring them back. The traditional button has not appeared, and the option to do so under "History" is greyed out. A previous answer pointed me to the "profile folder", but I have no idea how to do anything useful there, and anyway, there's no "sessionstore.js" that I can see. Or is that the problem, somehow?
