Sorry, Firefox fans. The chances of Mozilla's Firefox browser being ported over to iOS are just about zero, as in not now, probably not ever. That\u2019s the word from Mozilla, which this week pulled Firefox Home from Apple's iTunes Store, saying it will focus its resources on other projects.\n\tWhile Mozilla, the open-source group that developed Firefox browser and the Thunderbird email client, didn't explicitly say it will never write for iOS, it's clear from the context that Mozilla can't work with the tight restrictions Apple has placed on browser developers.\n\tInstead, it will continue to construct its own operating system known as Firefox OS, built on Mozilla\u2019s Web technologies, in much the same way Google built the Chrome OS on its Web technologies. Firefox OS, Mozilla CEO Gary Kovacs said in a blog post, will be optimized for entry-level smartphones and will first launch in Brazil early next year.\n\t\u201cAs billions of users are expected to come online for the first time in the coming years, it is important to deliver a compelling smartphone experience that anyone can use,\u201d he said.\n\tThe decision to kill Firefox Home wasn't surprising; it was never a full-fledged browser. Instead, it was a Safari add-on that allowed users to synch bookmarks, open tabs, and browsing history between a laptop running Firefox and an iPhone. I never could get it to run decently on my iPhone, and I ditched it pretty quickly. It\u2019s one of the few, maybe the only, Mozilla product I really didn\u2019t like.\n\tThere is a version of Firefox for Android, although it doesn\u2019t necessarily run on all flavors of the operating system and the many Android smartphones on the market. (Here\u2019s Mozilla guide to Firefox on Android.)\n\tIf you\u2019re curious, here\u2019s the scoop on Apple and browser developers: Apple won\u2019t let real browsers compete with Safari in the iTunes Store. Instead, developers must build wrappers around its Safari browser.\n\tWhile developers of some decent alternative browsers, Opera Mini comes to mind, manage to live with that restriction, Mozilla decided it could not and pulled the plug. I\u2019m not blaming Apple. Keeping very tight control over its platform and applications that run on it has helped create a very solid experience for users of iPhones and iPads. Google, on the other hand, has opted for a much more open approach. That gives developers a lot more freedom to develop applications, but sometimes results in seriously flawed and insecure apps.\n\tIn the long run, the choice of mobile browsers is becoming much less significant as apps, not Web pages viewed via browsers, become more and more central to mobile computing. Still, I\u2019m sorry that I\u2019ll never be able to load Firefox on my iPhone.
