Firefox OS will need to successfully compete against BlackBerry OS, Windows Mobile, bada and the other quite obscure mobile OSes long before it'll have a chance to even begin competing against Android or iOS. Many of these alternative systems have actually shipped on numerous devices, and have actual users.
And how exactly is it "different"? Firefox OS is really just a limited subset of what we already have available (and have had for years, in some cases) under these various existing systems. We can already quite successfully run HTML5/CSS/JavaScript-based apps on Android, iOS, and BlackBerry OS for instance. And this is ignoring Firefox OS's inflexibility when it comes to using languages other than JavaScript (sorry, Asm.js and Emscripten are hacks, at best), or writing native applications.
It's hard to see how it'll compete on vague notions of "openness" that most consumers really could not care any less about, while failing to compete on things that consumers do care about, like functionality and experience. It can't even really compete on price, given the existence of Android.
