We are using Azure AD Conditional Access to protect our services, and require all users to have a Domain Joined (AD) or Compliant device (Intune Policy), but Domain Joined devices isn't recognized when using Firefox. It is working for IE, Edge and Chrome, but not Firefox. We have activated SSO for Firefox, so that is working, but the necessity to provide proof of being correct domain joined isn't working. I cannot not find any articles saying it should work, but the upposite. My issue is I have been told it used to work, but for some reason it doesn't work anymore.
