My Groups get dumped when I shut down from Firefox and I have to rebuild them...
I set up the groups and they seem to be fine until I shutdown Firefox and then restart.. The groups disappear..

App tabs and Tab Groups (Panorama) are stored as part of the session data in the file sessionstore.js in the Firefox Profile Folder
Make sure that you do not use Delete browsing, search and download history on Firefox to clear the "Browsing History" when Firefox is closed because that prevails and prevents Firefox from opening tabs from the previous session.
