Andre Williams have you tested this managing method thru configuration profiles? As far as i know you have to manage thru ADMX templates by importing both fire fox and mozilla ADMX and ADML.

Andre Williams i found it here bro next time please dont give out false info without first testing.
Windows (Intune)
OMA-URI:
./Device/Vendor/MSFT/Policy/Config/Firefox~Policy~firefox/B_WebsiteFilter_Block
Value (string):
But i cant seem to add more than one website under the value.
The site below contains all templates just in case if anyone needs it.

Andre Williams just curious where did you get this? Because I don’t see the policy name nor string name of block sites in both fire fox ADMX and ADML.
