/**

 * This test only tests values in an about:blank document that opened in a popup

 * Because there is no interaction with a third party domain, there's a lot fewer tests

 * Covers the following cases:

 *  - RFP is disabled entirely

 *  - RFP is enabled entirely

 *  - FPP is enabled entirely

 *  - (A) RFP is exempted on the popup maker

 *  - (E) RFP is not exempted on the popup maker
