At least provide some feedback in the form of a simple message. Whenever you open a configurations page and it’s blank any sane person would think something is broken and not “Ah, but surely I need beta or nightly builds for this to be working!”.
Also how would I block auto refreshing? Add-on? I have a couple of important sites that I visit every day. Some idiot of a developer decided to implement auto refreshing (probably for the ads, which I’m blocking anyway ). So now the page would refresh automatically every 2-3 minutes unless I’m playing an audio stream there. And if I pause it, here we go again…Now think about the fact that on your smartphone you are quite often using mobile data. You get the picture.
Both nightly and beta serve completely different user bases. I mean plural because there is also a difference between people who go for te beta and people who go for the nightly. I don’t want to try out new features. I just want to use a normal browser and tweak settings that are actually there but not made available to me. If someone says “But there is an add-on for this and that” I would simply reply like this: using an add-on to change a configuration that is already there is an oxymoron. Add-on is called add-on because it ADDS something extra ON top of the base. Plus more add-ons increase browser instability and vulnerability.
