Firefox – How to Recover Tabs After Clicking ‘Start New Session’ in Firefox

firefoxsession-restore

user1264624 asks on another website:

After a Firefox crash, I accidentally clicked "Start New Session" instead of "Restore". Unfortunately there is no way to get back to the previous session as the other possibilities to restore are deactivated to click them, looks like the sessions is completely lost.

Is there a way to get it restored?

I did try about:sessionrestore, but no luck,
about:home but there's no session restore available, from History menu it's inactive to select.

Please do suggest any possibilities to restore the session (Note, I did not close the Firefox window nor I restarted the system once I lost the session but using a new session in the same window)

Firefox 3 stores its session data in a JavaScript file located in the user profile folder. To restore an accidentally discarded session, simply:

  1. Quit Firefox.
  2. Replace the current JavaScript file with the backed-up version.
  3. Restart Firefox.
