This theme makes the seemingly outdated Thunderbird look good again amongst all the other beautiful e-mail software out there.

I originally found the theme via OMG!Ubuntu article, which linked to the upstream of this add-on (in GitHub). However, it seems that this fork is much more up to date. In fact, running on OS X I had an issue, posted about it on GitHub, and the developer had it fixed within an hour. So, very responsive developer, beautiful theme, what more could you ask for?
