    Bug 1372072 - Part 2: Add a test case for check whether network information API has been spoofed correctly when 'privacy.resistFingerprinting' is true. r=arthuredelstein,baku
    
    This adds a test case to test that network information is correctly spoofed when
    'privacy.resistFingerprinting' is true.
    
    Firefox ESR 52 does not have the navigation object inside workers. Thus, the
    worker test was removed.
