Well, Apple is also definitely to "blame" for forbidding Gecko on iPhone, a number of years ago. I may be wrong, but I seem to remember that there used to be a prototype build of Firefox Mobile that ran on iOS, but Apple made it clear that it would not be accepted on the Store. Developing an Apple-compliant Firefox for iOS would mean developing an entirely separate browser, which basically wouldn't share a single line of code with either Firefox Desktop, Firefox for Android, Firefox OS or Firefox for Firefox OS, plus it would be using a (reduced version of) WebKit, so it would not have the same behavior as the other Firefoxen and it would require yet different Firefox Development Tools. If this platform was a high priority, this might be feasible, but it might take several years, at the expense of some other project and Apple would still be in position to shoot down Firefox for iOS (again). So I don't think that this is going to happen any time soon.
