Firefox gets paid by Google. A lot. Maybe part of their agreement is to not implement some features because it would compete with Chrome. I don't really know, and I don't really care what Firefox does or doesn't do. I only care that Apple does not allow other browsers to use their own browser engines. Opera mobile also implements the APIs I need (on Android). Even MS Edge supports the APIs. Firefox can join Apple in being lame, I don't really care.
