Apple will introduce new versions of iOS and OS X at its annual developer's conference.
Mozilla Planning to Release Firefox iOS App in the Future
The statement about releasing Firefox for iOS marks a major shift in ideology for Mozilla, as the company has, in the past, repeatedly said that it would not offer a version of Firefox for iOS because of Apple's refusal to allow third-party browsers to use their own web engines. In 2013, then VP of product Jay Sullivan said that Moziila didn't "feel like it could build the browser it wants" on Apple's platform, and that it had "no plans" for an iOS version of Firefox.
An inability to provide custom web engines along with the lack of an option to set a third-party browser as the default browser makes it difficult for companies like Chrome, Opera, and Firefox to create satisfactory browsing experiences on Apple's platform. Though little is known about Firefox's plans for iOS at the current point in time, it is likely Mozilla will need to continue to work within Apple's limits.
Though Mozilla's Firefox browser for iOS will be subjected to Apple's restrictions, key Firefox features like accounts, customizable home panels, and data syncing will translate to iOS, helping Firefox users achieve a more seamless browsing experience on a range of devices.
