About UserJS

User Javascript, also called UserJS or userscript, can be used for many things. It can fix websites that are broken in Opera, it can add features to sites, to make browsing them more enjoyable. Userscripts can even be used to add features to the browser itself. The Firefox equivalent is called Greasemonkey. While a lot of greasemonkey scripts can work with Opera, not all do, the files on this site have been tested for use with Opera. The UserJS files on this site have been divided into six categories, for more on those see the list on the right. Installation instructions can be found on every script's page.
