This document is intended specifically for existing users of
Enigmail, who want to start using Thunderbird 78 and its integrated
OpenPGP functionality.
If you have never used the Enigmail Add-on, then you can skip this
document.
Due to required technology changes, you'll experience a lot of
changes. We have tried to make the new OpenPGP functionality easier
to understand and use, but on the other hand, some features will
work differently than before, or might be missing.
Before you update to Thunderbird 78, you should read this whole
document, to understand the changes that you will see.
