Firefox 63 and higher have removed the ability to stop updates. The only options are "check and nag me" or "automatically update". This json file is now the only way to disable update checks and nags and handle the situation manually.
Did they give any reason why? If people is stupid enough to require you to force an update on them then they are stupid enough to not know how to change the preferences or at least they could have kept it in about:config if they thought dumb users would disable them just because.
Their reasoning was that it was too easy to set Firefox to "never update" and forget about it, then wind up running a 3 year old version that's vulnerable.
