This is not resolved.

 

Right now if I get a login prompt from GitHub while I'm using Firefox, it asks me to enter my password. If I change my user agent to Chrome, still using Firefox, it properly adds that I can press a button on my security key to log in.

 

So U2F is still being blocked in Firefox based purely on user agent.
