User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.9) Gecko/20100101 Goanna/3.0 Firefox/45.9 PaleMoon/27.0.3 Build ID: 20161214135803 Steps to reproduce: As shown below, I added 'child of contact' & 'child of contact-inbox' as folders to my 'contact' account. (Note: There's nothing significant about the word "contact"; it's just a name.) [a] contact | [i]__ Inbox | | | [i]__ child of contact-inbox | [i]__ child of contact Key: [a] account icon, [i] inbox icon. I used the FolderFlags add-on to mark both 'child of contact' & 'child of contact-inbox' with "Sent" & "Inbox" flags. Actual results: My 'contact' account spontaneously started using 'child of contact' as the its inbox. No subsequent mail went into Inbox, it all went into 'child of contact'. Expected results: The 'contact' account should have continued to use its normal Inbox. Is TBird using 'child of contact' because 'c' comes before 'I'? ...Oh, wait; Actually, it doesn't. Neither "child of contact" or "child of contact-inbox" are found as strings in 'prefs.js'. Is TBird malfunctioning? Is it making a wise decision regarding what to use as an inbox?
Work any better with 52?
