title: Mozilla FireFox page controls changing based on authentication type
body: <p>I have a .NET MVC web page that contains 3 radio buttons for choosing a value on a form. In a certain test environment that offers two methods of authentication (user/pass or certificate), the radio buttons will change to checkboxes when the page is loaded. This appears to happen when using the user/pass method, but not the certificate.</p>
  
  <p>Browser version is FireFox 52.3 in the environment where this is being tested.</p>
  
  <p>Need to check if it is using a moz-appearance style, but I don't think so.</p>
  
  <p>I suspect that it might have to do with security zones, based on the differing behavior between authentication types.</p>
  
  <p>Has anyone experienced this type of behavior before? Suggestions for what to try?</p>
