Exhibit A: You can't tell the GMail app to use anything but Chrome (at least on iOS).
I'm sure there are more such examples. Even if a default was changeable the initial setting (as we saw in the Microsoft vs. Europe over IE) is very powerful.
and for whatever reason (i'll give benefit of doubt its a bug), every time i open a link it asks me which browser to use, no matter how many times i set the default to firefox.
i dunno, whenever i open a link it had radio button that says "use this to open links every time?" and i click yes then select firefox. but ya doesnt work so apparently you can't.
