Hello,
the problem with missing PGP support in Thunderbird is in CentOS 7 and CentOS 8.
Also installing Thunderbird via snap give the same problem.
Where are the settings for this installation stored - not in ~/.thunderbird?
Ok. it is in ~/snap/thunderbird
I have now installed Thunderbird from
thunderbird-102.2.1.tar.bz2
https://www.thunderbird-mail.de/herunterladen/
in my /home-directory as ~/thunderbird and it works well.
with regards
Ch. Hanisch
