Not anytime soon. Until it has a large share of the market, it won't be worth the time for developers to really come aboard, and the only way to get there is to have a large enough sized team driven to be better than iOS and Android, which they don't have yet, and probably won't, sadly. The mobile web trend has started to die back down, too, according to recent stats; writing apps in JavaScript for FFOS would make sense if it were just a matter of reusing the same served content.
But, I'd like to see FFOS do well. David against Goliath(s) sort of thing.
