Agree.
Not at all a security expert here, but maybe doing it inside a distrobox could be a temporary fix?
Forget it, I just tried and it seems it gets installed in your home directory so using distrobox doesn’t change anything (apparently, but as I said I’m not an expert so feel free to correct me if I’m wrong).
However, I’ve seen they also have it available through a bunch of package managers like nix, arch and Fedora
Imho the card view redesign was more than needed, thank you!
Big kudos to the thunderbird team, since the supernova announcement they’ve done a really good job
