Intune Joined Devices on Firefox

Firefox for Enterprise Security

Hello,

Our organization is attempting to implement a Conditional Access policy that restricts access to certain websites to Intune joined devices only. The error message mentions that I need to enable a setting from within Firefox called Windows SSO, mentioned here: https://support.mozilla.org/en-US/kb/windows-sso. This setting is already enabled and I am still getting an error.

Is there anything else that could be causing this?

We had a similar issue. Even with Windows SSO enabled, Firefox needs to be version 91+ and the device must be Intune compliant. Also, check network.negotiate-auth.trusted-uris in about:config. Edge often works better with Conditional Access.

Would you mind opening a bug here:

https://bugzilla.mozilla.org/enter_bug.cgi?product=Core&component=Networking

The networking team can help research what is happening. We have lots of logging for this.

what version of Firefox are you using?
