title: Javascript imitate Chrome "+" button
body: <p>I want to a create new tab with JavaScript not on the address about:blank. The address on my target page according to window.location.href is "chrome-extension://gibkoahgjfhphbmeiphbcnhehbfdlcgo/iframe.html".</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-js lang-js prettyprint-override"><code>window.open("chrome-extension://gibkoahgjfhphbmeiphbcnhehbfdlcgo/iframe.html", '_blank');</code></pre>
  </div>
  </div>
  
   The code above seems to open about:blank not the target page. How to fix this issue?</p>
