WARNING from the moderator team: userChrome.css scripts are not provided by Mozilla and is not officially supported. Firefox is a work in progress and, to allow for continuous innovation, Mozilla cannot guarantee future updates won’t impact your customizations. For this reason, Mozilla does not officially support style rules customization.

Please read Firefox Advanced Customization and Configuration Options to learn more.

If you want to make a custom theme, I recommend that you head to https://color.firefox.com/

Here are some links. I have added a blank space to each of the external links so you will have to remove those.
