+**Note**: though comments are used in this readme file for documentation, comments are not valid in actual JSON files. Remove all comments before attempting to deploy.

+Some of the policies were originally only available on the ESR for security reasons. As of Firefox 62, these policies are available outside of the ESR, but only via JSON file or a Local Machine-based Group Policy. User-based Group Policies are not allowed to set values for these policies. The descriptions below mark such policies as "Machine only".
