"At Sony Mobile, we continue to evaluate innovative technologies that can help deliver the premium user experiences that Sony's consumers expect. Our engineers are now working with Firefox OS Mobile and HTML5, evolving technologies which show great potential."
The OS is being pitched as an alternative to Android for low-end smartphones in developing markets and is built for applications written using HTML5.
The first phones using the OS are all powered by Qualcomm processors and will be offered by Alcatel One Touch, LG Electronics and ZTE starting this summer. Huawei Technologies also said it will also come out with products later this year.
