Firefox for iPhone adopts Safari’s bottom search bar

More and more, in mobile apps/UI, we're having features at the distance of the thumb, and for some reason we haven't yet been able to do away with this visual reference that comes from a different age and different method of interacting with a machine.

More over, phones are so big these days that having an input bar at the top of the screen, that get's used all the time, can be considered a UX non-sense. I really wish this becomes a design trend.
