app tabs don't reopen when I restart Firefox
I pinned GMail, Facebook, and Twitter as app tabs, and then exited Firefox and quit it completely. When I restarted Firefox, the app tabs were gone. According to the help system, the app tabs are supposed to come back, and that's what I want. What gives?

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" if Firefox is closed because that prevails and prevents Firefox from opening tabs from the previous session.

I added the addon but it did not solve the problem. :(
