Policies aren't part of Firefox, so if you have policies then your IT department likely added them and you will contact them if you have questions.

Are those rules added via a policies.json file in the distribution folder or added via GPO rules in the Windows Registry ?

Thank you for all the answer, yes maybe it is added the policies by IT department.
