A few months ago came a new phone-oriented operating system, Firefox OS, which promises much. Although the range of devices on which you can run Firefox OS is still tiny compared to Android, has attracted the best expectations, according to early users who anticipated and have installed on their computers.
However, Firefox OS needs more coverage. To do this, the developer community has released an emulator that would allow you to run it from any PC, with full functionality of active hardware. That is, if turn the webcam, it will be activated on the PC as if it were a dedicated device and if you use the rotation in applications that accept it, it will work.
To try Firefox OS, you’ll need to install the Firefox browser. The emulator will operate as a browser extension, so you never need to install any extra software. The emulator versions are available for Windows, Linux or Mac OS X.
The download file is not exactly small and about 60MB, because what you’re downloading is a complete simulation. Firefox asked to report bugs as arise, to help improve the simulator and the features of the Firefox OS that will be implemented in the future.
