Stylus allows you to easily install themes and skins for many popular websites. It is the easiest way to customize your browser and make it unique, as it offers a great collection of useful UI skins, skins for popular websites and easy installation of themes from online repositories.

Stylus is one of the easiest userstyles managers you can find. It allows you to install themes from popular websites like Instagram and Pinterest, or to create and manage your own. You can also install a theme from an online repository if you don't want to take the time to create your own.

Besides the ability to install and configure userstyles, Stylus also offers an API and a sandbox where you can use it as an example to learn how it works. So you can download it to see how it works and make sure you are not breaking any rules.

Stylus can also be used in private mode, which is why it needs permissions to access the network and access the clipboard.
