Works as it should. Now, not only theme is dark but also preview of the message.

It's not working on Thunderbird 78.8 64bit Fedora Linux 32. To be clear, I'm expecting the message pane to be "dark moded" but it is not.

Dark Reader is one of my favorite addon in Firefox. I'm so glad that it is now available in Thunderbird!

It's the Thunderbird dark theme but it includes the messages too. Now everything is in dark mode. This is just what I wanted.

This add-on switched the tab provided by the "Open Google Calendar" add-on to dark mode as well. A+
