Previous session lost after crash :(

Firefox crashed and now my previous session is greyed out/not available. I have my profiles folder open, but not sure if I save the sessions files in time. Might have been replaced with the newest session already. Can I use any of the files in the sessionstore-backups folder to find a backup point, and how?

The kinds of files you may find among your sessionstore-backups files are:

  • recovery.js: the windows and tabs in your currently live Firefox session (or, if Firefox is closed, your last session)
  • recovery.bak: a backup copy of recovery.js
  • previous.js: the windows and tabs in your last Firefox session
  • upgrade.js-build_id: the windows and tabs in the Firefox session that was live at the time of your last update

Please copy them all to a safe location so Firefox doesn't replace or cull them.

Could you take a look at what you have and the date/time of the various files to see whether you think any of them would have the missing tabs?

I fixed it with the copy/name change method! Thanks jscher2000 I found some of your advice in other threads and it worked!
