I use Firefox over any other browser precisely because I can "hack" it. I've changed so much under about:config that I have to document it for the next install. Firefox allows so many useful hacks that are truly in favor of the user. Chrome not so much. I don't use anything other than macOS or *nix, so I cannot speak to IE or other platforms.

Unfortunately, you are in a tiny minority in being able to do that, wanting to, and actualy getting round to it

Except that as of FF 48 you can't install unsigned addons, even if you allow it in the config.

It's like they're trying to give up every advantage.
