Not sure what they mean here as you can already do the things listed with config files and although it's been a while since I was doing it, I seem to recall at least one of those files were JSON. Happy to be corrected on that though.
I know, Mozilla - how about actually providing a mechanism to manage FF from AD Group Policies?
I'd suggest anyone thinking of deploying FF in any kind of commercial/production environment get a hold of CCK2 to do it.
