[CentOS] OT: Firefox lockdown policies for CentOS7 desktops

Hi all,

I am doing some tests with my CentOS7 desktop. I have configured a policy to lockdown Chrome/Chromium browsers and it works perfectly. And I am trying to the same for Firefox browsers but Firefox's docs are really "hard" to understand.

I have the following stopper points:

a/ what is the "real" system wide's config file: firefox.js, sysprefs.js or local-settings.js/mozilla.cfg ? b/ And what is the real directory: "/etc/firefox", "/usr/lib/firefox/defaults/pref" or which?? c/ Is it possible to download and install addons using system wide's policy? For example with Chrome/Chromium you can use "ExtensionInstallForcelist" option. d/ Where can I found all the options :)?

Many thanks
