@Micah-Omayio Thanks for reaching out and sincere apologies on this.
For Windows 10, you can use this SSO feature and try to perform the CA : https://support.mozilla.org/en-US/kb/windows-sso
For others platform like windows down level device, IOS and Android this is still not supported.
The way any device is identified for CA, is by accessing the Device Auth Cert from the machine store on device and presenting them to the Azure AD, Mozilla browser does not have a way of doing it currently and fails to perform the CA process.
