Firefox updates its iOS web browser to turn Tracking Protection on by default
I don't get the point of 3rd party browsers on iOS. When Apple doesn't allow vendors to use their own engines. I think Apple should be taken to court over that matter. Safari on iOS is the same as IE on Windows in the early noughts. If Apple could grant Uber privileged API access, i'm sure they can give Mozilla and Google the same permissions to build independent browsers on iOS.
