This app works within Firefox profiles, with images and codes embedded locally. Firefox fans can personalize their browsing without using internet bandwidth.

The app features a new 'Colors Code' feature, which lets you use your normal theme and apply different colors with gradients for the toolbars, menus, and lateral bands. For example, you can choose the same color with different gradients for each section. For the first time, you can even customize the lateral bands!
Opening the folder with the local gallery of solid colors, you can add as many colors as you want and choose between white, black, or moccasin text. If you want to reset your normal theme or unset/set the two colored lateral bands, it only takes one click. Plus, unlike other similar addons that play with colors, this one is completely free!
Overall, if you're a Firefox lover looking to take your browsing experience to the next level, give this app a try. It's intuitive, customizable, and offers something new with the colored menus and lateral bands.
