browser_hwconcurrency_popups_aboutblank.js (3318B)

      1 /**
      2 * This test only tests values in an about:blank document that opened in a popup
      3 * Because there is no interaction with a third party domain, there's a lot fewer tests
      4 *
      5 * Covers the following cases:
      6 *  - RFP is disabled entirely
      7 *  - RFP is enabled entirely
      8 *  - FPP is enabled entirely
      9 
     10 *
     11 *  - (A) RFP is exempted on the popup maker
     12 *  - (E) RFP is not exempted on the popup maker
     13 *
