Since I updated to Firefox 92 tabs don't restore when Firefox restarts

The setting Restore previous session, on settings, general, is marked. History is kept, and the previous tabs are on the history menu (no restore session option is available, however).

Things I tried: Started on safe mode. Deleted startup cache. Refreshed the profile. Turned off add-ons.

So far, nothing works. When I close the browser with tabs open and I open it again, it starts with my homepage only.

You may have corrupt sessionstore [v56] sessionstore.jsonlz4 file(s). Delete all sessionstore* files and the sessionstore-backups folder.

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

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.

That worked for a while, but a few restarts later, Firefox stopped restoring sessions again.
