I had several tab groups, but the last time I opened Firefox they'd all disappeared, and been replaced with an advert - can I recover my tab groups somehow?
I've set Firefox so it re-opens my old tabs every time I run the program, and also installed Tab Groups. Usually it opens all the tabs in all the groups with no problem, but this time they'd all disappeared and been replaced with a single advert. Is there a way to recover the old tab groups?

It's likely that by the time there is an answer the data to allow recovery will be long gone, but this really make me angry. I have been operating with the same tabs for months now, and by using tab groups... poof, now all gone. I use tabs precisely because digging around to find all these pages is a time consuming task. some I don't use for a week or two, but when I needed them, there they were. BIG BLACK MARK awarded to Firefox on this one! My trust level of this software, which had been very high just went to below IE, which is really saying something.
I managed to find how to do it:
History > Recently Closed Windows > Restore All Windows
I'm rather glad I found it, if I hadn't there'd be a load of research for essays and articles that I'd never have found again.
Make sure that you use Firefox > Exit of File > Exit to close Firefox with all open windows.
Otherwise only the last closed window gets restored.
If you are lucky then you can restore the recently closed window(s) via History > Recently Closed Windows like posted above.
