Same thing here : Fedora 33, Thunderbird 78.3.1, TBSync 2.18, can't find de TBSync options to configure it ... Any suggestions ?
EDIT : My bad, didn't read the 3rd screeshot "How to open the TBSync account manager" carefully enough : it was in the bottom-right corner of thunderbird.
Sorry, and thanks again for the good work !
