title: DOMException: Failed to read the 'localStorage' property from 'Window': In Chrome Incognito mode and running in Iframe
body: <p>Can anyone please help me on this issue as I'm getting this same error message on my site when I run it inside iframe of a separate domain in incognito mode only? You can access site from <a href="https://www.seguros.es/presupuesto-moto.html" rel="noreferrer">here</a>.</p>
  <ul>
  <li>No issue on non-incognito mode.</li>
  <li>No issue without iframe as working an individual site</li>
  <li>No issue with those sites that don't use localStorage even running inside iframe or without iframe</li>
  </ul>
  <p>Error in console -</p>
  <p>&quot;DOMException: Failed to read the 'localStorage' property from 'Window': Access is denied for this document&quot;</p>
  <p>Thanks</p>
