I'm ising Firefox on a Windows 10 machine. Lately any time I open a new window it insists on opening several dozen tabs from previous sessions. I cleaned the cache. No change. I rebooted. NO change. I uninstalled it using an installer (Revo) that supposedly checks for all kinds of leftover files. I then rebooted. I saw no signs of it on my machine. I downloaded a fresh copy and installed from scratch. When I open the initial page it's fine. As soon as I open a new page all the old things are back in a gazillion little tabs. It's kind of annoying. Not to mention the time it takes to close everything by hand.

Any suggestions will be appreciated.

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