For those who don’t know yet, Firefox OS is a new Linux based mobile operating system, built by using the new HTML5 technology by the Mozilla developers. For now, it is used as default on smartphones with modest hardware specs, developed by LG, ZTE, Alcatel and Geeksphone, while Firefox and Spreadtrum are already working on a 50$ Firefox OS based phone.
Despite the fact that the newest Firefox OS version available on devices is Firefox OS 1.3, a preview of Firefox OS 2.0 is already available and it looks quite awesome, for an OS targeting low-range and mid-range devices.
