StopTheScript is a Safari extension for iOS, iPadOS, and macOS that stops all JavaScript on your selected websites. StopTheScript is the only Safari extension that stops inline JavaScript on the web page as well as externally loaded JavaScript. This is in contrast to Safari content blockers, which can only block external JavaScript, not inline JavaScript. Why StopTheScript? If the button still pops up an alert, then your JavaScript blocker is incomplete, and you need StopTheScript!
