Thunderbird 78.2.2 released with a number fixes and one new feature

Thunderbird 78.2.2 is now available for download. Version 78.2.2 will be offered as an update package to the Thunderbird 78 branch. There is no corresponding update package for version 68, so you cannot get Thunderbird 78.2.1 automatically installed over Thunderbird 68 or older releases.

Thunderbird is my preferred email client of choice. I use this app on every PC and on every operating system I use. It is stable, contains all the features you need, supports add-ons and also comes with a useful RSS reader. I am using Thunderbird for many years and never felt the need to look for an alternative.

Thunderbird 78 doesn't support classic XUL add-ons any more, but includes some of their features natively. E.g. on Windows you can minimize the app to the system tray.

Thunderbird 78.2.2 comes with the following changes.
