Rated 5 out of 5 stars

I also registered to comment because ers2258 acted like a jerk. This theme is great. I have been using it for a while now on both Thunderbird and Firefox, and everything else (e.g. the default themes) just feels clunky and way too bright. I wish EVERYTHING had a DeepDark theme. In fact, because of this theme, I've actually installed the stylish add-on and have made some of the pages I visit regularly resemble it because I like it that much.

After the latest Thunderbird update destroying this theme, I'm reluctant to update my Mozilla software. I wish they would push out security fixes separately from the aesthetic stuff.

Anyway, Steva, sorry ers2258 was a jerk. The rest of us really do appreciate all of the work you've done on this theme in the past and hope you'll get the new one out whenever possible. Thanks for an awesome set of themes.

This review is for a previous version of the add-on (3.0.6). 

Thanks for your review and support. It helped me to remind me that there are also lots of people who still have respect for others work :)
