Firefox OS Simulator 3.0 is up, you can download it now
The Firefox OS
Now available is Firefox OS Simulator 3.0 which lets developers and the plain curious check out the OS in a PC window. As an add-on to the Firefox browser, the simulator is easy to install and it takes less than a minute to do so. All you need to do is to run your Firefox browser, click on tools and go to Web Developer. From there, click on Firefox OS Simulator.
The most interesting of the new features is "Push to Device," which allows apps being used on the simulator to be "pushed" directly to a device running the Firefox OS. A rotation simulator and a geo-location feature allow developers to test out their handiwork without using a physical device. Besides Sony, other manufacturers that have agreed to build a Firefox OS powered device include ZTE, LG and TCL.
