The interface is different now but the old version did have a whitelist with ajax.googleapis.com, outlook.com, google.com etc. already entered. I go through that and delete anything that isn't Mozilla, ebay, or paypal related. Places I use on a regular basis and know I can trust. This version is neutered and doesn't have all the options it used to.
Be careful if you try to remove it... I uninstalled it earlier, and everything was broken... : [
