Created attachment 472371 [details] Sample Safari web extension Xcode project According to the Console Command Line API, $event is equal to the current DOM event while JavaScript execution is paused inside a DOM event listener. https://webkit.org/web-inspector/console-command-line-api/ However, $event does not work in Safari extension DOM event listeners. Steps to reproduce: 1) Download, unzip, open, build, and run the attached sample Safari web extension Xcode project EventBug. 2) Enable EventBug in Safari. 3) Open the attached sample HTML in Safari. 4) Open the web inspector. 5) Create a mousedown event breakpoint. 6) Click in the web page. 7) In the content.js mousedown event listener, enter $event in the console. Expected results: MouseEvent Actual results: ReferenceError: Can't find variable: $event
