Firefox OS was too ahead of its time. It made web technologies a first class citizen for mobile app development, well before mobile browsers were as capable as they are today. Back then, Apple and Android used their million-app inventory to eliminate rival platforms....you needed an app to do anything on a phone back then. Today, nobody's installing new apps if the function can be done on the website.
