Normally after I restart my computer everything in Firefox works just fine. I have the "restore last session" turned on and it will load my last session. But the last two times I've restarted my computer I have to resign into my Mozilla account, "restore previous session" is not an option, I have to reinstall my add-ins. It fortunately still has my history but it's a super big hassle as I keep browser tabs open to remember things.

I'm on a 2020 MacBook Pro running version 10.15.7 and I'm using Firefox version 80.0.1.
