Don't know what are you talking about, Firefox on Android is currently the fastest browser there. Chrome is slower and buggier on every new update.

My main slowness/bug with Firefox for Android is the sluggish scrolling. When I move my finger, there's a small but noticeable delay before the page starts moving. I don't have this problem with Chrome on my Nexus 4.

Like I said, I prefer Firefox for its desktop-like features. But in my experience, Chrome has a faster response in the UI.
