Downside: 1. Do you really know what your apps are doing? You can't compile from source.
2. You may only use apps Apple approves. So no Firefox for you.

This effectively means that Firefox on iOS has no support for extensions or addons like on Android... Because Apple and Safari doesn't allow that.
It's definitely not what people have come to expect from Firefox over the years, but at least I get to seamlessly sync my bookmarks, history and passwords with my desktop browser of choice.
