So Amazon audible popped up a firefox session with a talking book after I shutdown. So firefox saved this session to restore next time.

I shut down firefox while I:

1. I understand the file sessionstore.jsonlz4 in session store is a backup of the old tabs. So I saved it

2. I then copied it to the sessionstore folder under the profile. (I only have one folder under the profile folder so it must be the correct target). As a precaution, I also copied the file and renamed it previous.jsonlz4 and recovery.jsonlz4

But I cant get firefox to load it. Firefox stubbornly loads the tabs i just used and then creates new files called previous.jsonlz4 and recovery.jsonlz4 which overwrites my backed up files

So my question is how do I make firefox use the backup file I saved?

TIA/gary

You do not have to place the sessionstore file you want to restore in the sessionstore-backups folder, but this file needs to to at the main level.

You can copy a file from the sessionstore-backups folder to the main profile and rename the file to sessionstore.jsonlz4 to replace the current file with Firefox closed.

  • make sure to backup the current sessionstore.jsonlz4
