RESTORE PREVIOUS BROWSING SESSION

Hello there :)

Please help me restore my browsing session :(

For the past several months I have been using Mozilla, and the feature to restore previous browsing session has always worked well. Even after I clear the most recent history or remove the most immediate cookies, this feature would still work e.g. after I restart my PC or just restart the browser. It would restore all the tabs I was using previously including the most recent tab I was on before the browser closed or restarted. However, this morning, I tried to clear my immediate browsing history as I usually do and the browser froze while I was in the process of clearing this immediate history (continuously displaying the pop-up window/interface for clearing history and not allowing me to do much else on the browser - I couldn't even click anything on the tab I was on, nor could I navigate to another tab and/or open a new tab; and only the close button, and maximize window button, and minimize window buttons were responding). After waiting for a while for it to start working again, I got frustrated and I closed the browser.

I then opened the browser again, but this time, it didn't restore the previous browsing session and didn't even take me to the last tab I was on.

What could have happened this time around? It has not behaved like that for this whole year.

NB: I have not done anything to the browser after opening it! I am still on the same page it landed on when I opened it (just in case).

Thank you for your response @ jonzn4SUSE

Ever since this event happened (i.e. failure to restore previous session occurred after I re-opened Mozilla) Mozilla has been open since and it's still currently open (I haven't closed it nor tempered with it since opening it); so do you suggest closing it again so as to see these other restore files e.g. previous.jsonlz4 (because currently with Mozilla open, I can only see these two files i.e. the recovery.jsonlz4 and recovery.baklz4 files which were created today probably after I opened Mozilla after just previously closing it in frustration)? Is that a safe move?

Backup the session files in the sessionstore-backups folder in the Firefox profile folder to make sure not to lose possible important session data. Do NOT close Firefox when Firefox is already running.

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

You can check the upgrade.jsonlz4 file from the last update or use a utility to browse Windows System Restore points to see if you can find a recent sessionstore.jsonlz4 file.

You can look at this tool to inspect a compressed jsonlz4 sessionstore file. This tool works locally, no uploading done.

Did you check "History -> Restore Previous Session" and "History -> Recently Closed Windows/Tabs" ?
