I refreshed FF because it was slow to start. Now, I've lost all my groups tab.

I am running Ubuntu 14.04. I still have a "Old Firefox data" folder on the desktop, despite having ghosts to a previous installation (using Norton Ghost, running Windows in a system dual boot).

Is it possible to cancel this unfortunate "Refresh" FF please? I lost 80 + tabs and I will be very reluctant to "Refresh" FF ever...

sessionstore.js is closing Firefox and not so Firefox is running.

You can save session files in the sessionstore-backups folder in the Firefox profile folder to keep possible significant session data.

previous.js (cleanBackup: copy of sessionstore.js from previous session that was loaded successfully)
recovery.js (latest version of the sessionstore written during runtime)
recovery.bak (previous version of the sessionstore written during runtime)
upgrade.js-<build_id> (backup created during an upgrade of Firefox)

You can copy a file in the sessionstore-backup folder to the main profile and rename sessionstore.js file to replace the current file (make a backup of the current sessionstore.js).
