Comment 71 for bug 39376

I think the last thing we want is a hidden config options editor like about:config, gnome settings, or regedit. I think it a bad approach and once we set the precedent we will end up with a lot of untested, unstable, hard to find, and hard to understand options (like we have in all of those cases). Hidden options should be hidden only because they are known to be incomplete, unstable, working poorly, or no one has found a good place for them yet. Options that are intended for people to use normally should be properly organized.
