title: Open new browser window from popup
body: <p>I have a webpage (A) that opens a popup (P).</p>
  
  <p>In P, I have a link that must open a new _blank target page in the original browser instance (the one with page A).</p>
  
  <p>How can I accomplish this?
  I've tried some solutions based on <code>window.open()</code> but I am not sure how to apply them.</p>
  
  <p>Thanks a lot.</p>
