Firefox ADM Templates for Group Policy

Managing Firefox Settings via Group Policy With ADM/ADMX Templates

Following on from deploying Firefox via an MSI installer in an organisation, the next step for most admins is controlling its configuration centrally — proxy settings, homepage, extension policy, and so on — rather than leaving every setting up to individual users. Mozilla publishes official ADMX (and legacy ADM) templates specifically for this. Download the current Firefox policy templates from Mozilla’s own GitHub repository or support pages, then add the .admx/.adml files to your Group Policy Central Store (or the local PolicyDefinitions folder on a machine running the Group Policy Management Console) the same way you would for any other application’s administrative templates. Once added, you’ll find a new Firefox policy section under Computer Configuration > Administrative Templates (or User Configuration, depending on the policy) in the Group Policy editor, covering settings like proxy configuration, homepage enforcement, extension allow/block lists, and update behaviour — apply and link the policy to the relevant OU as you would with any other Group Policy setting. You can download the official Firefox ADM/ADMX policy templates directly from us here: Firefox ADM Group Policy Templates. See also our Firefox MSI installer guide if you have not deployed Firefox itself yet.

Still the Right Source in 2026

Mozilla’s own GitHub repository, mozilla/policy-templates, remains the current, actively maintained, official source for the Firefox ADMX/ADML Group Policy template files — nothing has changed about where to get these or how they’re distributed since this post was written.
