After nearly two years of development, Mozilla officially launched Firefox OS devices in stores, and has opened up payments for developers interested in charging for their apps – or charging for content inside their apps. The first commercial Firefox OS devices arrived in Spain, ready to be sold by Telefónica on July 9th; Poland, Colombia, and Venezuela also will have launches in the near future. Mozilla is starting by undercutting the low-end market to build momentum, but that’s not to say that higher-end devices aren’t in the pipeline for the future.
Fresh off its debut at Mobile World Congress in Barcelona, Mozilla’s mobile FirefoxOS now has perhaps its biggest early adopter: Twitter. Engineer Manuel Deschamps says Twitter for FirefoxOS will be available in the app store from the first day the devices begin to ship. The app mirrors the layout on other mobile operating systems, with the same Home, Connect, Discover, and me tabs. It will also support Firefox’s unique Web Activities feature, which will allow users to tweet a photo from any app that also suports Web Activities, which includes the built-in photos app.
