My computer has been having some problems lately: Any rough handling might trigger the computer to shut off instantly or restart automatically. This is likely a hardware issue, probably a loose battery or something. The Firefox-related issue is that sometimes, upon turning the computer back on, something odd happens to my browser session: It is set back to three months earlier. The recent browsing button show everything having been browsed three months ago; but when I check my history, all my most recent tabs are there. This is tedious whenever it happens, as I have to spend about an hour manually opening everything I've lost (that I want to keep) from history. If there's a way to bulk re-open a bunch of tabs, I don't know how. All that has become something of a routine annoyance (it happens maybe once every two months) but I'd gotten used to it and it wasn't really an urgent problem. Today, however, I dropped my phone on my laptop, triggering a restart and a blue screen with a message that said something like "we're cleaning things up for you." It's what usually happens when I drop something on or accidentally elbow my thinkbad. (More commonly I move my computer a little bit and it just shuts off completely, goes black.) Before this happened I was due a firefox update, and I found it had done so when I turned my computer back on. I realised immediately that I had lost some tabs, and I assumed that it was just a three month setback. Upon opening my recent browsing though, I found out with horror that I'd been set back nine months. I cannot restore from a nine month period manually. I don't have the time, energy or willpower. I'm asking here if anyone knows how to bulk restore tabs from history or how to restore my session to how it was just a few hours ago. Thanks
