Not able to restore previous session

Firefox became unresponsive and I closed the program. Upon reopening it, I could not restore my previous session like I normally can. This only happened a few minutes ago.

I've have two files that I found in the Firefox folder sessionstore-backups (BAKLZ4 file and JSONLZ4 file) if you need them.

被選擇的解決方法

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.

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
