Rated 5 out of 5 stars

It is definitely the best "theme-based" add-on you can get for Thunderbird to this point & the most beautiful dark theme I have ever seen as well. Hint: Don't forget the 'special-colored' versions when you dig deeper into Steva's world.

This guy just put so much effort in to make it work again, after classic theme styles stopped working with the release of Thunderbird 68...we really have to appreciate it a lot.

Trust me, if you are a dark theme lover, you have to get this add-on and if you still doubt it then just look at the reviews for the "old & now incompatible" version of TT DeepDark.

Thanks Stefano & greetings, Thomas H.

Hello Thomas,

Thank you very much for your feedback about my add-on. Makes me really happy when I see that users appreciate my work and, even more, when they feel all the time, dedication and passion I put into it.
