Ah. If we’re talking mobile, all bets are off. FIDO prompts require Apple and Google to provide the necessary APIs for third-party devs to use, and are still somewhat new. It’s likely that since iOS browsers are still just re-skinned WebKit (until the EU stuff settles and Mozilla implements Gecko on iOS), FF on iOS can leverage the OS APIs, but making it work with Gecko on Android requires more work.
I was referring to desktop, where those limitations aren’t a hindrance.
It’s a temporary ban. That is less of a consequence than what you’d face for airing a little too much copyrighted content or something, except for saying shit that could have come from Hitler’s mouth.
