What is Ultimate Theme creator?
Ultimate Theme creator is a Firefox add-on that allows users to create and share their own color theme for Firefox. With the highest level of customization, users can choose their preferred colors for different parts of the browser UI and see the changes instantly. Themes can be named and shared, but there is no storage capability, so saving the theme as a JSON file is advised for future reference. Users can also apply shared themes by pasting the JSON contents. The add-on also allows users to reset to the default Firefox theme.
