Mozilla won’t bring Firefox to iOS until it can use its own rendering engine via The Verge.
Jay Sullivan, the company’s vice president, told an audience at SXSW that Firefox won’t be coming to Apple’s platform until Cupertino relaxes its stance toward third-party browsers.
I’ll echo Gruber’s comment about no one holding their breath for Firefox for iOS. There are already a bunch of browsers on iOS, all do basically the same thing and other than a couple of differentiating features, they’re all the same. No need for another one, and frankly even if Firefox for iOS could run it’s own rendering engine, why would I use it? There’s just no leverage there.
