  <p>As per the above SO post I tried using <code>target="_blank"</code>. As expected, when the link is clicked the page opens in a new window.</p>
  
  <p>However -</p>
  
  <p>Using  <code>target="_parent"</code> in Chrome opens a new window each time, but Firefox is not working. According to <a href="https://developers.google.com/apps-script/guides/html/restrictions" rel="nofollow noreferrer">https://developers.google.com/apps-script/guides/html/restrictions</a> <code>target="_parent"</code> is not supported by <code>HTML Service</code> — this is probably why it behaves like <code>target="_blank"</code>.</p>
  
  <p>Using <code>target="_self"</code> in both Chrome and Firefox results in the first click opening in the same window but subsequent clicks bring up a blank page.</p>
  
  <p>I want the page to load in the same window as my Apps script, as would occur when using <code>target="_self"</code> in an anchor on an unrestricted web page.</p>
  
  <p>plz help me. </p>
