  1. RPID is Origin w/ Firefox attestation mode (Firefox 55)
  2. RPID is Domain String w/ Firefox attestation mode (Historical anomaly)
  3. WD-05 Mode (Firefox 56)
  4. Firefox 58 Mode

You can open this page inside an iframe for testing as well, or open a cross-origin iframe (which is prohibited and will give an error).

You can also load this page on port 8443 to test that alternate ports work for a given RP ID.

To use this to test Web Authentication support in Firefox, be sure you're using Firefox 60 or later.
