Intune policy not applicable for multi-session AVD

[Sunyix11]

Hi,

We are experiencing an issue with the application of Firefox policies on Intune-managed multisession Azure Virtual Desktops (AVDs).

Following the Firefox documentation, I created an OMA-URI-based Intune configuration profile and assigned it to a device-based group containing multisession AVDs.

OMA-URI: ./Device/Vendor/MSFT/Policy/ConfigOperations/ADMXInstall/Firefox/Policy/FirefoxAdmx
Data type: String
Value: Copied all of the text from the latest firefox.admx

and configured some supported settings (New tab page and Disable Firefox Account)

This method works correctly with Intune-managed physical laptops; however, it is marked as "not applicable" for multisession AVDs.

We also attempted an alternative approach. We imported the firefox.admx and adml files into Intune and created a Firefox policy based on the imported administrative template. We configured a device-based setting, "Disable Firefox Accounts (device)," set it to enabled, and assigned the configuration profile to a device-based group containing multisession AVDs. Unfortunately, the configuration profile is again marked as "not applicable."

Is it possible to manage Firefox browser with Intune policies on multisession AVDs?

Thank you in advance!

I don't have any insight into multisession AVDs specifically, but I don't know of any reason this wouldn't work.

All Intune is doing is mirroring the value to the registry and we read it from there. So the question would be is the setting make it to the registry.

On the Firefox side, you can go to about:policies and see if there are any errors.

I stumbled here researching other issues. OMA-URI and Custom Templates aren't supported by Intune on multi-session.I think you would need to script it out.
