Mozilla finally officially announced the minimum requirement for mobile phones that will use Firefox OS. And, from a list of the specifications mentioned by Mozilla, it appears that low end mobile phone of Firefox is not too different from other platforms. To run Firefox OS operating system, Mozilla set some standards, such as minimum processor speed of 800 MHz, 256MB RAM and screen with QVGA resolution (320 x 240 pixels). Compared with other platforms, the minimum requirement of Firefox OS is similar to minimum standards for mobile phones with Windows Phone OS.
