'Sup tech support. In Firefox, when I move my cursor over the back or forward buttons in a downward motion, it shows a list of pages I can go back or forward to. If it's a new tab/window and going back isn't an option then this doesn't happen of course, and the same is true if I move over the forward button when there's nowhere to go forward to. I figure it's a new "feature" of some kind and so I'm assuming there's something I can do about it in about:config. But I don't know where to start. Does anyone?
