  • Hi,

    Thanks for your post.

    GPO settings are all aim at Microsoft web browser IE, not guarantee to take effect on third-party web browsers.

    This might be managed by third party ADM / ADMX file. Of course, they were not prepared by Microsoft:

    https://addons.mozilla.org/en-us/firefox/addon/gpo-for-firefox/

    http://sourceforge.net/projects/firefoxadm/

    You could also ask help in Firefox support forum:

  • Thanks for posting your query on the forum. ASAIK, you can use firefox.js and customize the values of "preference extensions.enabledScopes" to block extensions that are in the extension directory of the Firefox installation and other restrictions.

    Regarding the Group policy option, i can think of adding the ADMX/ADML files to the Policydefinitions folder.

    There is an open-source policy template available on GitHub that helps you integrate Firefox settings in Group Policy. Download the Policy Template for Firefox and copy the files to the Group policy store.

    Note: By default the Firefox ADMX/ADML files are not present.

    Once done, navigate to this path:

    Computer Configuration > Administrative Templates > Mozilla > Firefox > Addons

    Here you will get a setting called 'Allow add-on installs from websites' which we can disable to disable the add-on installs.

    Hope the above information helps..!!!
