While Mozilla not allowing the New tab page override on mobile Firefox is indeed their problem (which greatly hinders more competent developers from fixing what Mozilla's own bunch of lazy and incompetent "developers" is both incapable and unwilling to do), you advertising this as a functional speed dial solution for Firefox is blatant false advertising. Without New tab override, your so-called "speed" dial is no faster than opening the Bookmarks menu. Don't lie to technologically literate users. I feel stupid for wasting time on your pointless extension.
