Tabs disappear and are not refreshed when I re-open Firefox. I've re-installed Firefox but the same issue occurs. I've checked the box to re-open tabs but no go.... Restore previous session is checked....

Chosen solution

You aren't using Private Browsing mode as that would prevent opening tabs from the previous session?

In case you use "Clear history when Firefox closes".

  • do not clear the Browsing History
  • clearing "Site Preferences" clears exceptions for cookies, images, pop-up windows, and software installation and exception for password and other website specific data
  • clearing "Cookies" will remove all selected cookies including cookies with an allow exception you may want to keep

Does Firefox update the files in the sessionstore-backups folder ?

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.

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)

I had clear browsing history on. Turned that off and my tabs are now restoring.

Thanks
