Your first point at least is an iPad thing. Nothing is fully featured on the iPad. Not even safari. It's thanks to that exact fact that chrome is at least mostly fully featured on the iPad. If safari had comparable function, you could bank on them blocking those features from the chrome app too. There's a deal made somewhere. I wouldn't be surprised if cash flow from Google is why safari is still the same piece of crap it always has been. "Hey your R&D + return for safari only nets you 1% YOY. We'll give you 2% YOY if you just don't even bother."

They only know raising prices and knee-jerk reactions to competitive moves in their market space. Additional functionality for the user is only granted when it's being used as a cudgle against their competition. Never for users benefit.

If you're seeing new functionality on the iPad Firefox app, it's likely because Firefox figured out a way to implement it without paying apple because they want the user to have that function. Totally different ethos.
