Alcatel Mobile Phones, LG Corp. and ZTE Corp. are developing mobile phones to run on Mozilla’s new Firefox OS mobile operating system, the open-source software group said. In a release Monday, Mozilla said the devices will launch in at least nine countries this summer, including Brazil, Colombia, Hungary, Mexico, Montenegro, Poland, Serbia, Spain and Venezuela. Mozilla said it will announce other markets where the phone will be available soon. Mozilla, which is best known for its Firefox web browser, said Huawei Technologies Co. will also start this year to develop devices running on Firefox OS. “Firefox OS smartphones are the first built entirely to open Web standards, enabling every feature to be developed as an HTML5 application,” the release said. “Web apps access every underlying capability of the device, bypassing the typical hindrances of HTML5 on mobile to deliver substantial performance. The platform's flexibility allows carriers to easily tailor the interface and develop localized services that match the unique needs of their customer base.” Mozilla said 17 carriers have “committed to the open web device initiative,” including America Movil, China Unicom, Deutsche Telekom AG, Etisalat, Hutchison Whampoa Ltd., KDDI Corp., KT Corp., MegaFon, Qtel, SingTel Ltd., SmartTelecom, SprintNextel Corp., Telecom Italia, Telefónica S.A., Telenor Group, Telecomunicações Móveis Nacionais, S.A. and VimpelCom Ltd.. Linux-based open source computer operating system Ubuntu also launched a free, mobile device platform in January.
