They still caved. It's just Safari with a Firefox skin on it. Just like all other iOS browsers. Mozilla had wanted to build a REAL Firefox browser for iOS, but Apple wants to lock everyone into Safari.
Oh yeah, I know that they caved and that Apple doesn't allow any other browser engines on iOS. I was just pointing out that they held out for a pretty long time.
There is much more to a browser in 2014 than just rendering HTML and running JavaScript.
True. But can a browser without its own rendering engine really be called a browser? To me, Firefox without gecko just isn't Firefox. But, to an end user that just wants their bookmarks to sync and doesn't care about choice, it doesn't really matter.
