Thunderbird Release Notes

Version 78.1.1, first offered to channel users on August 6, 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 78.1.1 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.

OpenPGP in Thunderbird 78.1.0 has reached feature complete state, but it's still disabled by default, to allow more time for testing, correctness, and localization. See the wiki for how to enable and help with testing.

System Requirements: Details

Windows: Windows 7 or later
Mac: macOS 10.9 or later
Linux: GTK+ 3.14 or higher
