I'm looking for a way to effectively prevent add-on installs for Mozilla Firefox using Group Policy. &nbsp;The two settings I've found (Computer Config/Administrative Templates/Mozilla/Firefox/<wbr />Addons) are Allowed Sites and Allow add-on installs from websites. &nbsp;If I configure the 'Allow add-on installs from websites' it blocks any add-on install, however I need to be able to specify certain add-ons that <i>are</i> allowed. &nbsp;It doesn't seem to matter what I put in the 'Allowed Sites' GPO, if the 'Allow add-on installs from websites' is set to disabled.<br />

Anyone had any luck with preventing add-on installs in Firefox, while still allowing a specified few? &nbsp;The Chrome GPO templates make this super easy to manage. &nbsp;Just wish Firefox was the same way. &nbsp;I appreciate any help you can provide. &nbsp;Thank you.

How can I disable add-on installs for Mozilla Firefox with Group Policy, but still allowing a specified whitelist of add-ons that are allowed?

Mozilla Firefox is a free and open-source web browser developed by Mozilla Foundation. It is available for use on Windows, macOS, Linux, and BSD operating systems.
