I had to reinstall windows and lost the previously installed applications.

I had copied sessionstore-backups folder from previous profile folder.

Fter reinstalling firefox I am copying the old previous.jsolnz4, recovery.baklz4 and recovery.jsolnz4 into the new sessionstore-backups folder. But I am unable to restore my old tabs.

Please advize.

You need to copy recovery.jsolnz4 as sessionstore.jsonlz4 to the main profile level (i.e. that parent location where you have the sessionstore-backups folder).


You will normally find these files in the sessionstore-backups folder:

  • previous.jsonlz4 (cleanBackup: copy of sessionstore.jsonlz4 from previous session that was loaded successfully)
  • recovery.jsonlz4 (latest version of sessionstore.jsonlz4 written during runtime)
  • recovery.baklz4 (previous version of sessionstore.jsonlz4 written during runtime)
  • upgrade.jsonlz4-<build_id> (backup created during an upgrade of Firefox)

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).
