Application is one of factors that support the success of an operating system. If it is easy to develop application on an OS, it will encourage developers to create application. Many developers are more interested in open source OS.
The Mozilla’s OS for mobile device, Firefox OS, is an open source platform. Because it is based on HTML5, there will be many applications that can be run on this OS.
Carlos Domingo, Director of Telefonica Product Innovation, said that from their survey, 75% of applications on Google Play and AppStore are made based on HTML5 language, so it’s very easy to port those apps to Firefox OS. For the ease of searching applications for Firefox OS, Mozilla is reported to build a market place for its OS.
