How can I minimize Thunderbird 60.2.1 to tray after "MinimizeToTray revived" add-on stopped working?

After update, my Thunderbird stopped getting minimized with the "MinimizeToTray revived" add-on.
Is there any way to minimize my Thunderbird? Any other add-on that works with the new version?

Solution 1:

Birdtray is a system tray new mail notification for Thunderbird 60+. Birdtray checks the unread email status directly by reading the Thunderbird email search database, which makes it immune to Thunderbird API changes. As a result, Birdtray is a great Firetray alternative that shouldn't break on Thunderbird updates.

You can find the Birdtray source and instructions for compiling from source on GitHub. There is also a PPA you can use to install it in Ubuntu 18.04, 18.10 or 19.04:

sudo add-apt-repository ppa:linuxuprising/apps
sudo apt-get update
sudo apt install birdtray

Solution 2:

There is another add-on called "MinimizeToTray Reanimated" which claims to work with Thunderbird v60+.

MinimizeToTray Reanimated is an application mainly dedicated to Thunderbird to allow its minimization in the systray in one click. It is the update of MinimizeToTray Revived, which is not maintained anymore since the recent versions of Thunderbird.

Note: This add-on has not been reviewed by Mozilla yet.
