Need Help: Firefox SSO Setup Using Intune with Preferences and Policies"

I need help in applying Firefox settings through Intune to enable Windows Single Sign-On (SSO) for Microsoft, work, and school accounts. i need two changes as below

1. About:config setting

Create the preference:

network.automatic-ntlm-auth.trusted-uris

Set value to:

"xyz.com, abc.com"

2. Enterprise policy configuration via JSON

{

"policies": {

"WindowsSSO": true,

"Authentication": {

  "SPNEGO": ["https://xyz.com", "https://abc.com"]

}

}

}

My questions:

Can both the about:config preference and the enterprise policy settings be applied using a single JSON or ps1 script through Intune?

Or do they need to be managed separately (one via preference, one via enterprise policy)?

What’s the best way to deplo

y this via Intune? If someone can share one script to deploy the same, would be great.

Thanks in advance!
