The lack of the IOS version of the browser is probably due to the fact that the third-party web browser rendering engines are disallowed by Apple compared to Firefox for Android. The strange thing is that even the third-party browsers are making use of IOS rendering engine which may mean Safari but with different skin. However, it seems that things are changed and that Mozilla is planning to bring the IOS version of Firefox with its own different engine although I may assume that it targets IOS 7 and above that I still have yet to but the newer IOS device. Problem against that is that the Ipod Touch at minimum price is still expensive at $200+. Good thing is that there’s cloud synchronization of bookmarks, preferences, favorites and other stuffs in the IOS version as well just like the desktop version. What you can’t synchronize however, is the addons because not all addons are available on mobile version of the same web browser.
