title: How to handle ERR_INSECURE_RESPONSE in Google Chrome extension
body: <p>I'm doing simple GET request to my URL and I get the error "ERR_INSECURE_RESPONSE". THis is fine, as certificate is self-signed. But I have two questions regarding it:</p>
  
  <ol>
  <li>Is there a way to overcome this in extension? Like setting a flag in request or sth like that? (probably not likely)</li>
  <li>Is there a way just to handle this error (to notify user)? I've checked all XMLHttpRequest fields and cannot see anything that can indicate this error. Status field has value of 0 (zero).</li>
  </ol>
  
  <p>Any ideas?</p>
