KDE Neon provides Firefox with own APT repository, with pre-installed state. However, preinstalled Firefox does not support USB security keys like YubiKey 5.

STEPS TO REPRODUCE
1. Run pre-installed Firefox
2. Go to https://webauthnsample.azurewebsites.net/
3. Click Register or Authenticate button below. 

OR if you are worrying about security issues: Try GitHub login process with security key enabled account.


OBSERVED RESULT
You can see a pop-up near by the address bar, but it quickly disappeared.

EXPECTED RESULT
A pop-up that asks you to insert security key or enter PIN code to continue appeared under the address bar.
