Rated 5 out of 5 stars
I decided to register and post a review after reading ers2258's comments.
This is a fantastic theme. I've been using it for Thunderbird and FT Deepdark for Firefox for a while now. They are the best dark themes I have ever used for Thunderbird and Firefox.
I am grateful for the work steva has put into these projects in his free time, and appreciate how difficult/annoying it must be to try to keep up with Mozilla's new rapid release cycles. I am a programmer and completely understand how much effort it can take to create updates to fix things you didn't break. Don't let the few ungrateful people out there get to you.
Even if steva stopped updating these themes it wouldn't change the excellent work that was put into them. 5 stars all the way.
Thanks a lot for your review :)
