Rated 5 out of 5 stars

Nice addition! I wish Thunderbird and Proton collaborated more to make this type of thing more integrated.

Thank you! Works perfect with Proton Bridge account.

Can you please make it compatible with non-bridge accounts too? So that either it completely disappears or it shows correct status for GPG messages. (Normal Thunderbird GPG with non-ProtonMail account.)

Rated 4 out of 5 stars

Works as advertised by itself, but does not work with the Thunderbird Conversations extension. Also, would be nice if the box only appears for Protonmail mailboxes but not elsewhere.

Does what it says on the tin! Short and sweet codebase that's easy enough to verify personally, and doesn't ask for any crazy permissions.
