Hi, on a fresh Thunderbird 68, from extension menu, a try in installing Enigmail results in The addon could not be installed because it does not match the add-on Thunderbird expected. Looking at jsconsole, it gives 1600073931349 addons.xpi WARN Download of https://addons.thunderbird.net/thunderbird/downloads/latest/enigmail/addon-71-latest.xpi?src=search failed: Downloaded file hash (ed5b7bc728bbe80473a3fc43468055d7c9ac3182b62f48cec5f681cbfb341254) did not match provided hash (4156f187d8dec0b8c024389cf731051fb196f7469aa4c7c7623003d7adc4049e). It seems there is a mismatch with current version of thunderbird and provided supported enigmail.
