title: Chrome extension, after opening in tab, window.open() not working
body: <p>I created a popup in Chrome extension that works just fine.</p>
  
  <p>where in the popup, user will click on a button and open a new tab and loads a index.html that comes with the extension package locally.</p>
  
  <p>the index.html hv it's own .js files, css, etc.</p>
  
  <p>however, when a button is clicked inside the index.html, with window.open("url"), chrome failed to open a new window/tab from that page.</p>
  
  <p>error message:</p>
  
  <p><code>Refused to display 'https://www.behance.net/' in a frame because it set 'X-Frame-Options' to 'DENY'.</code></p>
  
  <p>what can i do the perform window.open() in a tab that is created by chrome extension?</p>
