title: Firefox Developer Edition get all event listeners registered on an element getEventListeners
body: <p>I want to get all the event listeners registered on an element, in JavaScript in the developer tools console.</p>
  
  <p>In Chrome, <code>getEventListeners(domElement)</code> exists.</p>
  
  <p>In Firebug, that apparently exists too. Firebug is discontinued. I found <a href="https://hacks.mozilla.org/2017/10/saying-goodbye-to-firebug/" rel="noreferrer">this article</a> which says:</p>
  
  <blockquote>
    <p>So it’s sad that Firebug is now reaching end-of-life in the Firefox browser, with the release of Firefox Quantum (version 57) next month. <strong>The good news is that all the capabilities of Firebug are now present in current Firefox Developer Tools.</strong></p>
  </blockquote>
  
  <p>Emphasis mine.</p>
  
  <p>However, <code>getEventListeners</code> is not working in my installation of Firefox Developer Edition  78.0b3.</p>
  
  <p>So how do I get a list of event listeners registered on an element in the console?</p>
