What's the monitorEvents() equivalent for FireFox?

Question

Google Chrome has a feature where you can run monitorEvents(document) and every event you fired will be logged in the console.

How can I get similar functionality in FireFox?

I came across this very outdated answer, but Firebug doesn't even exist anymore: Using Firefox, how can I monitor all JavaScript events that are fired?

Answer 1

You can try this

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);
  });
}
