Upgraded Thunderbird to 78.7.1. This version removes the Enigmail add-on and uses Thunderbird's built-in PGP support. They provided a migration wizard which does the export and import seamlessly. A major email client providing PGP support out of the box is a big step for email privacy.
The new version has a more modern look with flat icons.
I noticed that it shows quoted parts in a different color. There is better visual distinction between mails in a mail thread.
