While loading a page, errors, also known as Demdex calls, appear in the console.
A typical error:
"SecurityError (DOM Exception 18): Blocked a frame with origin \"URL" from accessing a frame with origin \"Demdex subdomain URL\". Protocols, domains, and ports must match | Audience Manager
This error also occurs in other browsers because jQuery.animate() sometimes tries to manipulate all frames on the page, causing a cross-domain security error in the iframe.
