Hi, Needing some help or clarification around an issue/bug with FireFox. I have FireFox running on a Windows 10 Machine and when visiting sites like Microsoft , there is an option to Sign in with Windows Hello or a security key which works like a charm. How ever when going to the same site using macOS and FireFox the option to sign in with a security key is not available as an option. I have checked the version of FireFox on both Windows & Mac and they are both 69.0.3 and I have also re-installed FireFox on macOS.

Is there anything that I am missing that is causing this not to work in macOS?

Thank You Ryan

Further to this I have also checked using Safari and the option to use a security key is available. This is only effecting FireFox on macOS.
