We'll see how "good" it is. I'm very skeptical about a Javascript-heavy OS being as good as an Android one on the same hardware. If all things are equal, it shouldn't be. However, I suppose Firefox OS will be more "feature-free" in the beginning, and those HTML5 apps will be a lot simpler than the typical native app, and these two things might compensate for the slower speed of Javascript. We'll see.
