Thunderbird Desktop
Version 78.2.0 | Released August 25, 2020
Check out the notes below for this version of Thunderbird. As always, you’re encouraged to tell us what you think, or file a bug in Bugzilla.
** Thunderbird version 78.2.0 is only offered as direct download from thunderbird.net and not as an upgrade from Thunderbird version 68 or earlier.** A future release will provide updates from earlier versions. Automatic updates are available for users already running version 78.0 or higher.
Add-on support: As of version 78.0, Thunderbird only supports MailExtensions. Your favorite add-ons may not have been updated for compatibility.
At this time, users of the Enigmail Add-on should not update to Thunderbird 78.
Originally it was announced to enable OpenPGP by default in version 78.2.0. It has been decided to slightly postpone this for final changes and testing by volunteers. See the wiki for how to enable and help with testing.
