How to integrate Firefox with Windows Group Policy

Mozilla has shipped the support for Windows Group Policy Support. Firefox 60 is the next Extended Support Release of Firefox browsers releases which replaces Firefox ESR 52.x. Firefox ESR 52.x is the last official version of Firefox that will be supporting the old extensions system. It is rather surprising that Mozilla made Firefox 60 the next ESR target instead of Firefox 59.

Mozilla Firefox uses autoconfig files that support an automatic configuration system for Firefox installations and hence this makes it compatible with the supported desktop platform. This is all supported by a new Policy Engine in Firefox that reads data directly from the Registry. This Registry is created by Group Policy Objects and applies the policies if they are found to be absolutely valid.

Firefox with Windows Group Policy

In order to check all the policies, you need to view the policies using the Group Policy Editor.

Firefox with Windows Group Policy

To view these policies, open Group Policy Editor.

To do this, open Run and type in gpedit.msc and hit Enter.

Or just search for Edit Group Policy in Cortana search box and select the Entry to open the Group Policy Editor.

Then navigate to this location:

Computer Configuration > Administrative Templates > Firefox and User Configuration > Administrative Templates > Firefox

Then the following policy template files are added to the directories on Windows:
