1 Policies can either be specified using the Group Policy templates or by creating a file called policies.json. On Windows, create a directory called distribution where the EXE is located and place the file there. On Mac, the file goes into `Firefox.app/Content/Resources/distribution`.

3 The content of the JSON file should look like this:
