Review for Enigmail by hlein
Rated 4 out of 5 stars
Does not work anymore with Thunderbird 63.0beta
This review is for a previous version of the add-on (2.0.8).That's correct. Release versions of Enigmail typically don't work with beta versions of Thunderbird. You have to use the nightly builds of Enigmail provided on https://enigmail.net/index.php/en/download/nightly-build
