Does not work anymore with Thunderbird 63.0beta

Cette critique concerne une version précédente du module (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
