[[!meta title="Migrating OpenPGP configuration from Enigmail in Thunderbird 78"]]

Since Tails 4.13 (November 2020), *Thunderbird* 78 replaces the *Enigmail* extension with built-in support for OpenPGP encryption.

If you used *Enigmail* before Tails 4.13, follow the instructions below to migrate from *Enigmail* to *Thunderbird* 78. Tails does not include *Enigmail* 2.2, the last version of the extension, which automates this migration.
