Announcement: Introducing the free Safari extension FindTheMadness

Description: FindTheMadness is a free Safari extension by the developer of the paid extension StopTheMadness. FindTheMadness detects when mouse and keyboard events in Safari are overridden by JavaScript running in the web page. When this happens, FindTheMadness informs you. By default, FindTheMadness displays prominent alerts in the web page, but it also provides the option to display warnings in the Safari Web Inspector Console instead.
