What is a User Script?

Violent Monkey Edge

Userscripts (a.k.a User Scripts, User scripts, or .user.js) are open-source licensed add-ons for web browsers that change web pages as they are loaded. They give users the power to make websites do what they want them to, rather than what was originally intended. This kind of script is usually file named on your computer as site it affects - what useful name you want to call it.user.js and always does end in .user.js.

Useful tasks like improving layout, fixing bugs, automating common tasks and adding new functions can all be done by userscripts. More complicated userscripts can create mash-ups by combining information from different websites or embedding new data into a web page, e.g. to add reviews or price comparisons to a shopping website.

Userscripts can carry out actions on your behalf and can potentially access any information on a website you have access to, or that you enter into a website. They are often permitted to carry out functions that scripts on normal websites cannot, such as storing information on your computer and sharing it between website. Badly written userscripts could potentially also be exploited by malicious websites.

To reduce security risks, most userscript managers let you control which websites a userscript can access and whether it can operate on secure (https) websites or local files on your computer. On OpenUserJS, the source code of every userscript is available to be examined, so that other programmers can see whether or not there is any malicious code or dangerous bugs.
