Why does FF close without warning and wipe out the windows and tabs that were open when it crashed?

This has happened randomly on several different computers, both windows and ubuntu linux. It just now happened on my Win 11 computer. Was viewing the CNN news site and FF suddenly closed, without a "FF crashed..." message.When I clicked the icon to reopen it, it came up with the home page group of tabs instead of reopening the windows and tabs that were opened when it crashed. Worse, none of the previous months of history shows up and recently closed tabs and windows are both greyed out.

Is there a way of recovering the history of what I was working on at the time of the crash and what the hell is causing this? I am close to dumping FF and going with something else as this is highly annoying.

Are there any valid sessionstore files in the sessionstore-backups folder in the Firefox profile 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> (backups created during a Firefox update)

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

  • make sure to backup the current sessionstore.jsonlz4

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

There are 2 profile folders in the \user_name\....\profiles location: one is the default one and one is apparently the one that is in use. Neither one has a sessionstore-backups folder.

Ok, sorry for the confusion, please disregard the previous post, I found it, so I will try the steps and post back.

There were only 2 files in the sessionstore-backup folder: recovery.baklz4 and recovery.jsonlz4

After copying them into the main profile folder, what names am I supposed to use when I rename them?

Ok, I copied recovery.jsonlz4 into the root directory of my profile, renamed it sessionstore.jsonlz4, restarted FF and the windows and tabs did not come back. All of the history is still gone. I used the scrounger and verified that recovery.jsonlz4 only contains the 5 or so tabs that are from the home pages setting.

So it appears there is no way to recover what I was working with prior to the crash, correct?

Ok, no response, so the answer must be that I am out of luck on that, so I'll start backing up the session files in order to be prepared next time it happens, while I am looking for a new browser.
