A userscript is a script that can change the way a website behaves. It is stored in a text file and run by your browser, which makes it very easy to install and update.

A userscript is useful for doing things that would be difficult or impossible with a simple bookmarklet, such as visiting many pages at once or automatically logging in to a site. Userscripts are also more powerful than Greasemonkey scripts because they don't require any extra software to run.

Userscripts are commonly used for:

Automatically adding features or changing the appearance (layout, colors, fonts) of a website; for example, adding a Facebook Like button to every page.

Security purposes, like blocking ads or scripts from tracking your activity on different sites.

Changing the functionality of a website; for example, making it possible to search directly from Google Images or making YouTube videos play in fullscreen by default

This extension will allow you to add your css / js code to every website.
