All the App Tabs disappeared when I opened Firefox after quitting. I understand that the App Tabs that I had set remains there if I close the browser and not quit. So does that mean that I have to create App Tabs every time I restart FireFox?

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.

If you use CCleaner then make sure that Session is unchecked in the settings for the Firefox application.
