title: Chrome Devtools console not working in certain websites
body: <p>I'm doing some studies in Javascript using Twitter website as example. In any website i can open Google Devtools and use the console to manipulate anything on the page, such as get DOM nodes, edit elements and so on.</p>
  
  <p>For instance, when i open 'www.google.com', go to Devtools and type the command above : </p>
  
  <p>console.log('testing');</p>
  
  <p>I get 'testing' string showing in the console.</p>

  <p>However, when i open 'www.twitter.com' and do the same thing, NOTHING happens. Nothing is shown in console, just an 'undefined' string as shown below :</p>
