Note that Enigmail will no longer let you manage your PGP keys, but instead will only provide a migration tool. Thunderbird will no longer use the system keyring and GnuPG; instead, it will handle PGP keys internally. To use your existing PGP keys with Thunderbird 78 and above, you must use the migration tool from Enigmail upon the first Thunderbird run. See the migration notes on the Mageia wiki. Also note that, to protect your keys, you should define a master password in Thunderbird.
