Just like Firefox Thunderbird can be customized with themes that give the email client a fresh look. Themes are installed just like add-ons in Thunderbird by opening the Tools > Add-Ons menu in the Thunderbird top menu and switching to the Themes tab on top. The install button is located on the lower left of that window. A file browser window opens that filters .jar files, the theme format Thunderbird themes come in.
The email client has to be closed and opened again before the new theme becomes visible. It also has to be activated from the themes tab in the add-ons menu before it becomes visible. The easiest way to accomplish the whole process is to install the theme, switch to the theme tab, activate the new theme and restart the browser then.
Many of the themes for Thunderbird at the official Mozilla Thunderbird website do not work with the latest version of Thunderbird which is surprising to say the least. It is probably possible to force compatibility but that has not been tested. All themes listed in this article are working with the latest version of Thunderbird which is currently 2.0.16. They probably will also work with Thunderbird 3.








Additional themes are available at the themes repository at Mozilla.com.

Is it me or are most of the themes listed very bad?
most of them… maybe… but Noia looks great!!! i use it in FF too and that for years now.
but, that’s only my opinion…
I love the Walnut because the icons are so densely packed in on my bookmarks toolbar. So far, no other theme that I actually liked has come close.
Strangely, no I don’t use it on Thunderbird. Hmm, weird.
Awesome list… i love them especially ACE CuteBird (Graphite), thnx
Gravity that’s the theme that I’m using right now ;)
The only theme that i would ever use for Thunderbird would be Black Japan, but the developer didn’t update it further than Thunderbird 1.5* . It also had an Firefox cousin but that one also got left behind.
The Black Japan Theme was the coolest ever..(still can be found on mozilla’s addons site).Could Someone update that theme to be usable in Thunderbird 3 and also for the Firefox 3.5 ? I’m begging right now .
I lack the knowledge but I’m willing to learn.. Could someone direct me to some tutorial? I want to update the theme myself but don’t know how to create themes for the mozilla software…
