Right. They keep the config settings around. They just start ignoring the value, like in the case of allowing unsigned extensions. Or anything related to telemetry and user experiments.

While I've not noticed any settings being ignored, I suggest to use policies(either GPO or "policies.json" when it comes to telemetry. As for experiments I've been running ESR for so long that I don't even know what these are supposed to be or do.

Wow, you didn’t notice the one I just listed even after I listed it? That level of ignorance takes effort!

As for telemetry, I’m talking about this particular incident, where the “user studies” feature was used to force an unrelated update:

You mean those settings that you don't get to see anymore when you type about:config unless you now, every fucking time, click "show me all settings"? The one they also removed entirely from the android release? That about:config?

Because they've been doing the exact same thing to that, packing it away more and more, slowly killing off the parts that made it a great power user and developer browser by just making them a little bit harder to use or get to every time.
