On my .NET MVC web page, I have 3 radio buttons for selecting a value on a form. However, in a specific test environment with two authentication methods (user/password or certificate), the radio buttons mysteriously change to checkboxes when the page loads. This strange behavior seems to occur only with the user/password method, not with the certificate authentication.
The browser version being used for testing is FireFox 52.3.
I'm thinking it might be related to a moz-appearance style, but I haven't been able to confirm that yet.
My theory is that it could be related to security zones, considering the different behaviors between the two authentication types.
Has anyone else encountered this issue before? Any suggestions on how to troubleshoot and fix this?
