Firefox OS is still at alpha stage towards to official release which expected to be happened on early 2014. It was still about a year to go. However, Firefox has approached Sony to build hardware for future Firefox OS devices. Sony had agreed and is working hard now in the Firefox OS development to associate with Xperia devices. Two days ago, Sony showed off their latest Firefox OS based running Sony Xperia E smartphone. Xperia E is a low-end smartphone which suit perfectly with early phase Firefox OS. The Firefox ROM is now available for Xperia E, download it and develop your own if you are interested. We expect more from Firefox OS in the next beta release soon.
