Using Firefox 3.6.18, I had several tab groups defined with several web pages in each group. I closed Firefox and my tab groups are gone.

The icon for tab groups is missing from the toolbar and I can't figure out how to get it back. Pressing CTRL+SHIFT+E does nothing. Under Tools, Options, General, the startup option is when Firefox starts, "Show my homepage" and it is greyed out. I have disabled all addons and the problems persist.

I don't understand why this feature just suddenly decided to stop working. I've decided to trust Tab Groups twice now and have been burned both times. This feature is a great feature, but if it is as unreliable as I've found it to be, I can't put my faith in using it.

How do I re-enable Tab Groups on my system, and how do I recover the groups that I had defined?

App (pinned) tabs and Tab Groups (Panorama) are stored as part of the session data [1] in the file sessionstore.js [2] in the Firefox profile folder [3].

Make sure that you do not use "Clear Recent History" to clear the "Browsing History" when Firefox is closed because that prevails and prevents Firefox from opening tabs from the previous session.

It is also possible to use the "Show my windows and tabs from last time" setting, that is usually a more reliable way to restore session data.
