Great, especially that it is downloadable from the official Mozilla site now. Previously you could only download it from https://github.com/mailvelope/mailvelope/releases/download/v2.1.1/mailvelope.firefox.xpi or so.

This is openPGP that just works.

Mit Abstand die einfachste und beste Möglichkeit, PGP-verschlüsselte Emails per Browser zu verschicken. Gute Schlüsselverwaltung.
