Firefox update crashed
I updated to version 80.0.1. Firefox froze when it restarted itself. After 15 minutes I closed it. When I started Firefox again, all my tabs had disappeared. I see no way to get them back. What do I do?

What about the rest of your profile? Settings, bookmarks, history, passwords . . . .
You may have corrupt sessionstore [v56] sessionstore.jsonlz4 file(s).
Delete all sessionstore* files and the sessionstore-backups folder.
Type about:support<enter> in the address bar.
Under the page logo on the left side, you will see Application Basics. Under this find Profile Folder. To its right press the button Show Folder. This will open your file browser to the current Firefox profile. Now Close Firefox.
Windows: Show Folder; Linux: Open Directory; Mac: Show in Finder
Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory.
Locate the above file. Then rename or delete it. Restart Firefox.
Don't delete the files if you need to rescue any data from
them, just move them out of the profile folder to some
location where Firefox doesn't look for them. You can
try to read out their contents using this tool:

That stuff seems to be intact.

Where do I find those files/folders?

Done.

I'm running Windows 10.
Linux: Under the page logo on the left side, you will see Application Basics. Under this find Profile Directory. To its right press the button Open Directory. Locate the above file. Then rename or delete it. Restart Firefox.
The above procedure found this folder: This PC > LocalDisk (C:) > Users > alanf > AppData > Roaming > Firefox > Profiles > dl1f50tv.default . I renamed the latter file to dl1f50tv_crashsave.default . I restarted the computer, then tried to restart Firefox. I got the message: "Profile Missing" "Your Firefox profile cannot be loaded. It may be missing or inaccessible." This also appears when I click on, say, an email link.

I did not try this, since I'm not really sure what file you meant by "Locate the above file."
What next?
Thanks for your help!
