It's really sad to see Thunderbird still doesn't support RTL in 2023, and if it was not because of BiDi mail ui extension, I'd have not ever used it. Also sad that this one don't have much votes
Well, its 2023 and still Thunderbird doesn't have RTL support. Still usable as far as BiDi mail extension exists and works. If it stops working, I'd forget about Thunderbird.
