// When WebAuthn is used from a web extension in Firefox, the effective origin

//
// As a non-standard extension of the spec, Chromium allows a web extension to
// claim an RP ID based on its host permissions
// <https://lists.w3.org/Archives/Public/public-webauthn/2023Dec/0078.html>
// This is reasonable given that an extension with host permissions for an
// origin could script a page to create/assert WebAuthn credentials with RP IDs
// that are valid for that origin.
//
// Since Bug 1956484, Firefox also allows web extensions to claim RP IDs based
// on their host permissions. An extension can claim <domain> or any registrable
// suffix of <domain> as an RP ID if
//  (1) the extension has host permissions for https://<domain>, or
//  (2) the extension has host permissions for http://<domain> and <domain>
//      is a loopback hostname.
//
// Firefox does not currently allow extensions to claim
// "moz-extension://extension-id" as an RP ID.
