Cannot access firebase from within an electron app

Trying to build an Electron app using ember-electron and am trying to use emberfire to communicate with Firebase. Everything runs fine when running as a web app with ember s but when launching as an Electron app I get nothing but errors like this:

XMLHttpRequest cannot load http://ift.tt/2wfqr92. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'serve://dist' is therefore not allowed access. The response had HTTP status code 404.

Is this a known problem or does anyone know a way around this? Unfortunately cannot simply add serve://dist to the list of authorized domains as Google doesn't consider it a valid domain name.
