Hi

What happens when you try to view that site in Firefox?

Is there any error message?

A pip makes a ball shape in the center of the screen goes around a few times and then the screen got blank. Sometimes the ball is colored and others it is just black.

Interesting... I have not used NFC since 2017, but could still login. see screenshot

What security software are you running besides MS Defender?

Do you have the same issue with Firefox in Troubleshoot mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode
