title: Disable Firefox's right click context menu in React
body: <p>I am trying to disable the context menu that pops up on right click for a specific <code>div</code>. In the render I do</p>
  
  <pre><code>&lt;div onContextMenu={(e) =&gt; {
      console.log(e); 
      e.preventDefault(); 
      e.stopPropagation(); 
      return false
  }}&gt;
  </code></pre>
  
  <p>and it does print so I know its attached, but it still pops up in firefox ESR 60.8.0 even though its blocked in chrome. </p>
  
  <p>Reason: I have a handsontable that I added a custom context menu to, and in firefox the native context menu renders on top of mine. Once I figure out how to block the context menu anywhere in firefox I will apply that to the handsontable in the custom renderer</p>
  
  <p>EDIT: started bounty because none of the other hacks have worked for me and this is a pretty obscure case about a rare version of firefox</p>
