ShadowFox was inspired by changes made in Firefox 57, which limited the amount addons could customize both the user interface and "protected" web pages.
This project aims at creating a universal dark theme for Firefox while adhering to the modern design principles set by Mozilla.
Our cross platform installer takes the guess work out of installation. With a few clicks of a button, ShadowFox can be downloaded or seemlesly updated without losing custom configurations. More Info »
ShadowFox is the most complete theme available, styling not just the entire user interface, but also "protected" webpages that aren't accessible to normal extensions, like about:preferences and about:addons.
Addons are one of the hallmarks of Firefox. Unlike any other theme, ShadowFox has custom styles available for the most popular extensions, like uBlock Origin, uMatrix, ViolentMonkey, Decentraleyes, Stylus and so many more.
