It's a bit sad that Firefox is caving in and shipping a browser using WKWebView. The rationale is that by using WKWebView they now get Nitro, and they have to "go where the users are" -- but a few years ago, it was a lot less clear that Android would be more prevalent than iOS.
Also, iOS seems like a fairly hostile environment for 3rd-party browsers since it's not possible to change the system browser -- that's probably why mobile Safari has such a large usage share on iOS.
