Every once in a while I lose my current window with all my tabs and an old window with 32 tabs replaces it. History doesn't show my current window.

I say "restore all windows" and that doesn't show my lost window. Let's simply this. How can I delete the 32 tabbed old window so I never see it ever in my lifetime or any future lifetimes. I am using the latest FF, Windows 10, 68.0.2 (64-bit). As it is I have to create a new window and look at history to restore my current tabs, inevitably losing some.

Is this a bug in FF or something I've added to FF? It only happens on this laptop.

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: https://www.jeffersonscher.com/res/scrounger.html
