Eight Beautiful Mozilla Thunderbird Themes

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.
Update: The installation process of themes in Thunderbird has been changed recently. You know need to click on Tools > Addons to open the email client's add-ons manager. Click on the small settings button in the top right corner next to the search form, and select install add-on from file from the selection menu.
Browse to the downloaded theme to start the installation. You need to allow the installation first, and restart the client afterwards to complete it.
Also note that some of the themes won't work in newer versions of Thunderbird. We have marked those specifically so that you know when this is the case.

You said that Outlook isn’t your main email client, so which is your main one?
I think its thunderbird
It is Mozilla Thunderbird.
Awesome! This actually solved my problem… what a stupid bug.
If this is the same bug that I’ve encountered, there may be another fix: (1) hover over open Outlook item in Taskbar, cursor up to hover over Outlook window item, and right-click; (2) this should give you Restore / Move / Size / Minimize / Maximize — choose Move or Size; (3) use your cursor keys, going arbitrarily N/S/E/W, to try to move or size the Outlook window back into view. Basically, the app behaves as though it were open in a 0x0 window, or at a location that’s offscreen, and this will frequently work to resize and/or move the window. Don’t forget to close while resized/moved, so that Outlook remembers the size/position for next time.
THANK YOU Claude!!! I could get the main window to launch but could not get any other message window to show on the desktop. You are my hero!!!!
Solved my issue! 6 years later and this is still problem…
Fantastic. Thank you. Size did the trick.
This solved my Outlook problem, too. Thank you. :)
