Rated 4 out of 5 stars

Works fine for me on Thunderbird 17.0 and win 7 32 bit. Would love to see this add-on with the icon set from Thunderbird 16.0 before color icons were lost in version 17.0. I've noted that the look of the color icons is enhanced on win 7 if you run thunderbird in XP 3 compatibility mode and turn off/disable desktop composition and Display Scaling.

This review is for a previous version of the add-on (2.6.0).

Email me (links are on my Home Page) and I can send you a test version with 16.0 color icons if you care to try it out.

Works TB v3.1.20 on XP Rated 4 out of 5 stars

Works with TB v3.1.20.
I changed the install.rdf to get it installed.
Using TB on Windows XP.
One thing: still v3 icons for accounts and in separate email-window.

This is a compact theme and only replaces the icons you see most often. It replaces the main toolbar icons and the main message window icons. I'm surprised that it works with TB 3.1.20! I developed it for TB 5.0 and above. Enjoy!
