A collection of custom CSS tweaks (userChrome.css/userContent.css) for customizing the Firefox browser UI. It provides prebuilt stylesheets and configuration files that users drop into their Firefox profile's chrome folder to restyle toolbars, tabs, and other interface elements.

Use cases

  • customize firefox toolbar and tab appearance
  • restore compact mode in firefox
  • make firefox ui look like classic versions
  • apply userchrome css themes to firefox
  • modify firefox interface beyond what webextensions allow

When to choose

  • you want deep visual customization of Firefox's UI that themes/extensions can't achieve
  • you prefer lightweight CSS-only tweaks without installing add-ons
  • you want maintained, regularly updated userChrome styles

When to avoid

  • you only need simple color changes - Firefox Color or built-in themes suffice
  • you expect CSS to add new buttons or toolbars - it can only restyle existing UI
  • you use a browser other than Firefox
