It really bothers me that all this information is available through JS (no, please don't suggest I disable it). Why does a website need to know the list of installed fonts? Why can they enumerate the list of "videoinput" and "audioinput" devices before they've asked for video/microphone permission? Why is information about how I've set various permissions (prompt vs. allow vs. deny) available? Exposing the visibility of menu/tool/personal/status bar is just weird (though for me all of them say "Visible", which isn't the case, so I guess Firefox is lying).
