Nightly builds of Firefox mobile OS are now available Mozilla has said. Firefox OS, code named Boot 2 Gecko, is Mozilla’s offering for a new and different mobile operating system and is based on Linux and Gecko. They claim that it will be more open than other OS such as Google’s Android. Firefox OS is HTML5 and browser based aimed currently at budget level phones and devices. This will make it easier for web developers, of which there are thousands, to make apps for Firefox OS using HTML5, JavaScript and CSS.
The process is similar to developing apps using the PhoneGap framework for making UI and hooking into the devices features, such as SMS, sound, GPS etc. This also means it will be easy to port existing app from Android and iOS to Firefox as over 70% already are made using HTML5. These current builds are not meant or suitable yet for running on smartphones or tablets, only on desktop for Win, Linux and iOS. Even then its not for the average user, as it is an involved  process to get it up and running, but for developers to get a taste, QA and other open research.

Firefox have the backing from 7 major carriers, Deutsche Telekom, Etisalat, Smart, Sprint, Telecom Italia, Telefónica and Telenor. The first devices with Firefox OS will be manufactured by TCL Communication Technology (Alcatel) and ZTE and will be released in Latin America first and then soon after coming to Europe. It won’t be easy for Mozilla to compete against the mighter Microsoft, Apple and Google, but sometimes a small player does manage to change the field, after all it was Firefox browser that took on Internet Explorers 90% dominance and now leads.
