Similar to the way Google has extended Chrome browser into an operating system, Mozilla has refactored Firefox into an OS for smartphones. The first Firefox OS phone, the ZTE Open, was launched for sale online in the U.S. through the ZTE company’s eBay storefront for $79. The odds of Firefox OS taking a significant chunk of the mobile OS market are very long, of course. But the widespread release of a mobile OS built upon HTML5 and bearing the name of one of the world’s most popular web browsers is an encouraging development for the open-source community in 2013.
