Friends, it's been a fun ride these past three years creating themes for Firefox and Thunderbird. With the introduction of the new Australis user interface, the developers have made theme development quite difficult with the constant changes in the UI code. I'm therefore abandoning further development and support of my themes. I am recommending Aris' "Classic Toolbar Buttons" as a good replacement for those wanting a more colorful UI. This add-on has many button icons to choose from, including the ones from my themes. Classic Toolbar Buttons works with Firefox, Thunderbird and SeaMonkey.

After using Thunderbird for some time now, I've become tired of the monochrome toolbar icons. I'm frequently clicking on the wrong ones for their lack of color. I feel that the plain "black" appearance is totally unappealing and makes the icons hard to distinguish between.
So, I've made themes doing a simple replacement to the mail-toolbar.png file in the default Thunderbird theme, with one that I've modified with different icons. I simply took the default file and changed the images.
These themes return the Main Toolbar, Compose Message Toolbar and Folder Pane Icons to the earlier Thunderbird icon sets.

This theme will work with Personas.
