The Mozilla Foundation on Tuesday announced that smartphones running its Firefox OS will be available to developers in February. The preview phones are being produced in collaboration with Geeksphone and Telefonica. The idea is to entice devs to create apps for the Firefox OS. “These devices have not been designed for consumers,” said Mozilla spokesperson Diane Zuniga. They run pre-release development versions of Firefox OS. The official launch of the OS is expected to take place later this year.
