A userscript is a kind of lightweight and less privileged browser extension written in JavaScript used to modify webpages. Userscripts may use the special API, usually referred asGM_API, allowing them to bypasssame-origin policy and store data in separate storage not accessible to web pages. The technology was initially introduced in theGreaseMonkey extension forFirefox web browser, and then spread to other browsers, sometimes built-in, like inPresto-based Opera, sometimes with help of extensions, like inChromium-based browsers. The most famous catalogs of userscripts areGreasyFork andOpenUserJS.
