Preface

Mozilla publicly demonstrated the open source Firefox OS in February 2012. Firefox OS is an initiative by the open source company Mozilla to develop a mobile platform for smartphones as well as a host of other devices, such as tablets and televisions. The reason for rolling out this platform was to provide its users with an operating system that has an alternative that respects the user's privacy and puts security first. Firefox OS devices are a great choice for users who are transitioning from feature phones to smartphones or those who are concerned about privacy. Mozilla is best known for developing pieces of open source software, such as the Firefox web browser, and it doesn't answer its users rather than answering to stakeholders. The aim of Firefox OS is to run on devices that have limited hardware capabilities while still providing a unique and smooth user experience.

Mozilla has a huge community of developers and users, and they are always willing to help others on platforms such as GitHub and IRC (irc.mozilla.org). Firefox OS also has a great marketplace. It has grown over the years and offers great applications. In Firefox OS, HTML5 applications are first-class applications, and so any ordinary web application can be turned into a Firefox OS application in just a few steps. Even the user interface of Firefox OS, which is known as Gecko, has been built with the help of three components, namely HTML5, JavaScript, and CSS3. This makes developing applications easy for people who have already done web development.
