Endless fun customizing the colors of the various user interface elements.

It's great and easy to use. Although I'd like to have an updated version of the preview for Firefox proton

Incroyable add-on, très facile à prendre en main.

The browser starts with the default theme, and it takes a while to reload the correct theme created by color.firefox.com

It would be nice to have an option to automatically change themes based on the time of day, but otherwise this is as comprehensive a Theme Customizer as I could hope for.

This is perfect

It works fine I like it. It helps to identify which profile is in use currently. 4 star because one of my preset define as a dark theme and many page understand this as a system theme is dark. It could be a great extra to set the dark and the day colors as well.
