Once again, I get no such option from Firefox. It closes everything without giving me a choice to save tabs. I'm using the latest Firefox on my old laptop with XP.

Tools --> Options --> General --> "Show Tabs and Windows from Last Session" works fine to set this on my non-nightly portable edition. I've just made this change, which is more to my liking, rather than having to manually click on "Restore Previous Session" each time I boot up FireFox.
