How to Add preferences to Firefox through Windows Server Group Policy

Hi everyone. I have installed Firefox on all windows 10 workstations and I have also installed latest Firefox Group Policy ADMX on Server. I need to set some preferences on all Workstations. The preferences that I want to set are the ones that can be found in about:config.

But the problem is that only some of these preferences exist in Group Policy by default and it says "deprecated". I know that I can add additional about:config preferences in a Group Policy object called "Preferences". But no matter how I enter the format or how I change the JASON file, no preference policy is applied to Firefox in workstations. By the way when I change "Preferences" gpo in group Policy the next Policy called "Preferences (JASON on one file)" does also change. I have thoroughly searched the web and Mozilla support and have tested all suggestions but all to no avail. Can you please help me and Give me an example of how to do that? I would appreciate any answer in advance.

Please read https://mozilla.github.io/policy-templates/#preferences

NOTE On Windows, in order to use this policy, you must clear all settings in the old Preferences (Deprecated) section in group policy.

thank you for the reply. this solved my problem. I really appreciate it. but I still have another question. I want to lock (force enable) "Block dangerous and deceptive content" in firefox settings and I have not found this setting in group policy objects. So I have to change it via "Preferences" in Group Policy via about:config records. I have been able to find the sub-items "Block dangerous downloads" and "Warn you about unwanted and uncommon software" in about:config and subsequently I have locked then through "Preferences" in gpo. But I haven't been able to find the parent record "Block dangerous and deceptive content" in about:config. How can I find it?
