For example, I like to keep Gmail (gmail.com) and Pocket (getpocket.com) pinned but when I close Firefox, I want it to remember my pinned tabs but automatically log me out of Gmail but NOT out of Pocket. I can get close to this functionality but Gmail's cookies seem to be tied to browser history. Pocket's are not. If this is not possible, is there a place I can make it a suggestion or is this something to do with Google. My privacy settings: nothing checked except 'clear history when firefox closes' -- under that: only 'download history', 'active logins', 'form and search history' and 'cache' are checked. Any help would be appreciated.
