Home was always weird. It wasn't actually a browser but sitll tried to sync your bookmarks, opening up Safari to view them. It was an experimental project, and it was no surprise that it ended.

Firefox for iOS is not just an experimental project. It's part of our core products now.

Firefox Home was an attempt to allow iOS users to access all their Firefox data without producing a browser called "Firefox" on iOS and not having it be a real Firefox browser because it was a UI on top of Mobile Safari. Mozilla has since given up and is producing a Firefox for iOS browser that's Mobile Safari underneath because Apple will not give in from their anti-competitive position of only allowing Mobile Safari as the browser on iOS. Chrome, Opera, Firefox, et al on iOS are all Mobile Safari underneath.
