It will better integrate services, including Firefox marketplace, Firefox Sync, backup, storange and even offer a service that will help locate, message or wipe a phone if it were lost or stolen.

"We’re pleased to see the Firefox OS ecosystem grow so quickly as users, developers and partners come together to experience and build the future of mobile experiences," said Andreas Gal, Mozilla vice president of Mobile.

"Firefox OS will continue to evolve and add more features to offer choice and customisation that is unmatched by any other smartphone.
