There is no Firefox browser for any iOS device from Mozilla. Any so called Firefox app for iOS that exists is fake or a shell from a outside party. Perhaps you are thinking of the unofficial Foxbrowser app. https://itunes.apple.com/us/app/foxbrowser/id550365886 Mozilla did have a app called Firefox Home up till mid 2012 if I recall that was not a web browser but for syncing with Firefox on desktop. Mozilla is looking at having a browser on iOS. It is not using the familiar Gecko and JavaScript engines that desktop and mobile Firefox (for Android) used though due to Apple's restrictions. http://swiftwala.com/firefox/ https://twitter.com/fennecios https://support.mozilla.org/en-US/kb/is-firefox-available-iphone-or-ipad
