What's the monitorEvents() equivalent for FireFox?

javascript jquery google-chrome firefox devtools

function monitorEvents(element) {  var log = function(e) { console.log(e);};  var events = [];  for(var i in element) {    if(i.startsWith("on")) events.push(i.substr(2));  }  events.forEach(function(eventName) {    element.addEventListener(eventName, log);  });}
