Mozilla Firefox has a setting now to support sign-in with Microsoft Work or School account. This is great news since it also means that we now can sign-in and get the benefits of Conditional Access Policies using Firefox browser. It will take benefit of your registered work or school account in Windows.
I have tested on a Intune enrolled Windows 10 Device with status “compliant”. I have CA policy that only enforce MFA if not device is compliant. Before I configured Firefox for SSO i got MFA prompted. But after change this setting I get nice SSO experience without the MFA prompt.
Here is the device status that is Intune enrolled.
And here is the setting I switched in Firefox in Firefox “Allow Windows single sign-on for Microsoft, work, and school accounts” we will get SSO and also CA policys that use compliance status will be supported in Firefox.
Great news for all Firefox users!
