Reason: CORS header ‘Origin’ cannot be added

What went wrong?

The user agent was unable to add the required Origin header to the HTTP request. All CORS requests must hav an Origin header.

This can happen if the JavaScript code is running with enhanced privileges allowing it access to multiple domains' content, for example.
