People have been asking for an add-on that lets them customize Firefox’s interface to suit there needs for quiet some time now and especially for one that you don’t have to restart Firefox to get a preview of or apply your theme.

Firefox add-on that easily allows your to change the background,text and colors of your browser. A great Firefox addon by Pavlos Touboulidis will help you customize as a preset or use any of the dozen included for quick access.

AnyColor is similar to Personas, a Mozilla Labs extension, in that you can use an image as a background, but the latter lacks the option to set basic colors. On the other hand Personas, allows users to use remote images and even a web page as the toolbars’ background which just expands the possibilities. You will need an account there as it is still labeled experimental.
