Hi!

I had two Firefox windows open at the same time, one with a lot of tabs open in it, and one with only a few open. I was going to close firefox in order to restart the computer, and closed the window with many tabs in it first, and then I closed the window with only a few tabs in it. The next time I started Firefox, only the window with a few tabs in it loaded, and not the other window in which I had the vast majority of all opened tabs. And I can't find any way to restore the tabs from the other window either. I have looked under the History menu, but I don't see any option to restore a previous session there, so I'm guessing that Firefox thinks that it already has restored the previous session when I opened it up again.

So, how can I restore the tabs I had in the other window, with a lot of tabs opened?
