I've heard that firetray doesn't close windows by default but rather hides them in the systray, which means they can restored in the context menu of the systray icon, but equally signifies they reappear when Thunderbird is restarted. To alter that behavior right-click the icon, select preferences, and unclick 'Closing window hides to systray', or alternatively 'Only last window can be hidden'.
