AnyColor is an add-on for Mozilla Firefox developed to give your browser a new look with new colors, transparency effects, and much more.
All you have to do is install the tool and restart Firefox to start editing the look of the browser with any of the preset themes it includes.

There are dozens of new themes to choose from, ranging from ones that modify just the background color to others that go further and place artistic images as backgrounds that are shown as slides behind the menu and browsing bars.
In addition, the program lets you add effects to the tabs, set slides, and even find new themes if you don't like the ones included by default.

This one is super good!
Well, I think it's very good, excellent, but only for those who know how to use it because I don't... or maybe it doesn't work?? If anyone knows how it works, tell me!!
