Using Firefox ESR along with GPO Templates. Since the issue with with a Firefox update we have not been able to force enable addons. Adding them in the correct group policy template will place them in the addons menus however it does not automatically enable them anymore. The key is successfully created in this location HKCU\Software\Policies\Mozilla\Firefox\Extensions\Install And in HKCU\Software\Policies\Mozilla\Firefox\Extensions\Locked I was only able to make the addon visible by manually creating the registry value in HKLM\SOFTWARE\Mozilla\Firefox\Extensions Has anyone seen similar behavior or have a possible workaround?
