superUserContent is a simple addon that creates a new directory in your profile's chrome directory called userContent.css.d. You can use this directory as a runtime path for css stylesheets. superUserContent will apply any stylesheets it finds in this directory to pages when they load.
- Changes to css files in userContent.css.d will take effect when the page refreshes
- Full compatability with other plugins and existing themes
- Use your own editor and CLI tools to maintain themes
superUserContent is for developers who want an easy way to customize the sites they frequently visit with their established toolchain. It can be used by theme designers who want to share their customizations on sites like userstyles.org
so they can be applied easily by casual browser users with addons like Stylish
This addon was made to address the current limitations
of userContent.css that make it difficult to use for general web development.
