 I can use my Android phone with Google Chrome (connected with

 as a WebAuthn security device.  When I try to register a WebAuthn device
 with Firefox, I get a pop-up that says:

    <site> wants to register an account with one of your security keys.
    You can connect and authorized one now, or cancel.

 And the only option is "Cancel" - I don't see a way to actually register
 anything.  Is there a way to use WebAuthn with Firefox on Fedora? 
I just checked at the Yubico demo site:

    https://demo.yubico.com/webauthn-technical/registration

There, the first prompt includes a Cancel and Proceed
buttons.  Then the next just has Cancel.

I also tried another test site:

    https://webauthn.io/

There, unless I uncheck "Require User Verification" in the
registration and authentication settings sections of the
"Advanced Settings" I have the same experience as you.  The
registration prompt from Firefox only has a "Cancel" option.
The Yubikey I was using did not blink and pressing it had no
effect.

Hopefully that helps, if only to confirm that it _can_ work.
I tested with firefox-105.0.2-1.fc36 before upgrading to
firefox-106.0.1-1.fc36 and checking that it still worked.

I've also used various Yubikeys on other sites with Firefox.
