I'm trying to setup a Mozilla.cfg file to lock down the installation of themes and extensions.
I have a config file that I've been working on and has been blocking a lot of what we don't want our organization to do, however I am unable to get it to block the installation of themes to Firefox.
I have both:
lockPref("config.lockdown.disable_extensions", true); lockPref("config.lockdown.disable_themes", true);
the ability to install extensions are locked down, however the user is still able to install themes from Mozilla Addons
