title: Gmail is having authentication problems. Some features may not work
body: <p>I am writing a Chrome extension that sends voicemails from Gmail Web App with Gmail API.</p>
  
  <p>I keep getting this red message somewhere around the time that I try to authenticate a user.</p>

  <p>My questions:</p>
  
  <ul>
  <li>Why is this happening?</li>
  <li>Can I somehow download Google Javascript Client library in a way that it doesn't create a global <code>gapi</code> variable?</li>
  </ul>
  
  <p>PS. I already tried reading the documentation. Also, the extension works fine, and Gmail works fine, the red message is the only problem.</p>
