Worked great initially for me, being used to Outlook. Unfortunately I had to disable it when I found out it was the reason I did not receive new mails anymore on one of my configured IMAP accounts.
It now shows it's incompatible with the current version of Tbird (52.9.31 32-bits).
Would enable it ASAP if it would be fixed.
