Firefox Home for iPhone is not a browser, but brings your desktop settings to your phone

Moziila says that its Firefox Home app is now ready to be installed from the Apple App Store to your iPhone. Before you get too excited, it should be pointed out that Firefox Home is not a full fledged browser. Instead, the app works with the free Firefox add on Firefox Sync and brings to the iPhone your bookmarks, browsing history and any open tabs you have on your home computer. If you don't have Firefox Sync installed, an e-mail will be sent to you detailing 4 steps that will install the program for you. Once that is out of the way, you can access on the iPhone, the information that is on your Firefox browser at home. This explains the "Home" part of the title Firefox Home. Mozilla has offered a pre-alpha mobile version of the Firefox browser, called Fennec, for certain Android models since last April. Apple's restrictions prevent Mozilla from building its rendering engine for iOS which means that Firefox Home will rely on the WebKit engine that is part of iOS to render pages. The software is available for free from the App Store for iPhone/iPod Touch models running iOS 3.1 or later. While it will work on iOS 4.01, it will not be able to use any of its features like the Retina display. As for the iPad, Firefox Home will work only on iPhone compatibility mode.
