I think he missed the point here. In Firefox everything gets treated more or less equally, whereas on the iPhone certain apps get treated better than others. For example, there's the whole "only allowed to use Safari renderer" nonsense.

I imagine the only apps on Moz you won't be able to remove would be ones that deal with system settings. To be seen, but there'd be no reason not to build it that way.
