Mozilla Firefox ADMX Templates and Group Policy Objects
Mozilla Firefox is a web browser that can be deployed and managed using Group Policy. IT admins can use Group Policy Objects to configure Firefox settings for their domain-joined computers.
This method allows administrators to bypass the unallowed app and unallowed browser lists on monitored Windows 10 devices. This method also enables administrators to deploy extensions.
Using ADMX Templates
ADMX files (and older-style ADM files) are a feature of Microsoft Group Policy software, which manages policies on computers running Windows operating systems. These are XML-based templates that describe both the user interface presented to a Group Policy admin and the registry values that should be changed on client computers if the policy is enabled or disabled.
The Firefox ESR version, which is designed for enterprise use, supports this kind of deployment via Group Policy, and Mozilla provides a set of resources and guides to help IT admins with the process. One of these is the Firefox for Enterprise Deployment Guide.
However, there are several limitations that plague ADMX settings in Group Policy. These include the fact that they’re not always backward compatible between versions of Windows, and that they’re often restricted to domain join or on-premise only. PolicyPak strips away these limits and maximizes ADMX settings in Group Policy. It also fills in some of the gaps that have long plagued Group Policy Administrative Templates.
Using ADMX Files
Firefox has supported Group Policy (GPO) settings since May 2018. IT admins can use ADMX files to configure the browser in their organization. To do this, they must first import the ADMX and ADML files into Microsoft Intune. They can then create a device configuration policy that will apply to their managed devices.
To get started, navigate to the Firefox Enterprise site and select “Get Firefox for your enterprise.” Then, choose the download option based on your environment. Once downloaded, you’ll find exe and msi installation files, as well as a deployment guide and the ADMX templates that you need to configure your GPO.
To set policies, click on the “Edit” button in the Group Policy Editor. You can also edit the policy using the Cortana search box by typing “Edit group policy” or selecting it from the list of entries in the search results.
Using ADMX Policies
Firefox policies can be used to configure settings in the browser for a domain-joined computer. They were first introduced in version 60, and have since replaced some of the options available in autoconfig. If there is a conflict between the two, policies take precedence.
Some of the Firefox policy settings you can set include autoplay, picture-in-picture, and a default value for the primary password. You can also configure proxy settings. You can also allow or block certain origins for popup windows. You can even prevent the user from changing the preferences for these features by using the locked option.
To get started, log in to a Windows server that manages group policies and download the latest Firefox policy templates.zip file. Next, open the Group Policy Editor and link the new policy to an OU that contains your PCs. You can then test the policy by logging in to a PC within the scope of the OU and opening Firefox. The policy should appear immediately. You can also use the gpupdate command to force the policy to apply.
Using ADMX Extensions
For IT admins to push out the Firefox extension, they need to first create a GPO and link it to an Organizational Unit (OU) that contains all the computers and users that they want to deploy the plugin on. They also need to download Firefox and Chrome ADMX templates and configure them as per their needs.
Once the ADMX files are downloaded and configured, they can be deployed using Group Policy Management on the Microsoft Windows server. The configurations can include enabling or disabling the Bookmarks Toolbar, Form History, Pocket and Private Browsing functionality. They can also set the default homepage and lock it.
They can also disable the Firefox built-in password manager, which will prevent users from saving logins or passwords on their computers. Additionally, they can configure the browser to not save information in web forms or search fields and block add-ons from being installed or updated. This will prevent users from bypassing the security of their workplace.
