Mozilla is working on integrating Group Policy Support for Firefox running on Windows devices in the upcoming Firefox 60 ESR release.
Group Policy is a feature of the Microsoft Windows NT family of operating systems that controls the working environment of user accounts and computer accounts. Group Policy provides centralized management and configuration of operating systems, applications, and users’ settings in an Active Directory environment.
The Firefox ESR (extended support release) is based on an official release of Firefox desktop for use by organizations including schools, universities, businesses and others who need extended support for mass deployments.
With this Firefox 60 release they are also introducing Policy Engine as a new feature for enterprise users to offer more configuration/customization support.
The Firefox Policy Engine through a configuration file will allow enterprise administrators to easily block domains, control pop-ups and plugins, handle default bookmarks, and control other behavior of the browser for systems.
