Recently when my computer shuts down (my battery is dying so it happens often) and the previous session are restored, they are not from my previous session per se, they are from an older session. What can I do for this to stop happening?

Thanks in advance

You can check for problems with the sessionstore.jsonlz4 file in the Firefox profile folder that stores session data.

  • rename/remove sessionstore.jsonlz4 and sessionstore.js

You may also have to rename the sessionstore-backups folder.

When sessionstore.jsonlz4 is deleted you lose pinned-tabs and open tabs and you will have to recreate them, so if necessary make a note or bookmark them. sessionstore.jsonlz4 is only present in the Firefox profile folder when Firefox is closed.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
