Mozilla's Firefox OS, is touted as an upcoming smartphone platform and is expected to rear its head in 2013. Recently, Engadget claimed that it has obtained screenshots of the Firefox OS Marketplace. The leak attempts to provide a better look at the apps that will be coming along with the platform and the Firefox OS Marketplace that will be providing them.

 "Mozilla has been seeding Firefox OS to eager developers for some time. However, we've largely been denied a peek at how the developer's own take on a mobile app store will play out on an actual device. Some of that picture just filled out thanks to some images of the mobile Firefox Marketplace that have landed in Engadget's hands," said the Engadget report. 

The Firefox OS platform is an open source operating system that Mozilla is developing for smartphones. The platform aims to support HTML5 apps written using "open Web" technologies rather than platform-specific native APIs.

The leak also indicates that the current store is a departure from the Boot to Gecko days "not to mention Mozilla Marketplace on the desktop" and is a "significant break from the top-level storefront."

Additionally, the Firefox Marketplace doesn't have the relative glamour and glitz that users come across with Google's Play Store and Apple's App Store; however, that could imply that the company aims to provide its users with fluff-free apps that are commonplace to the current platform-based app stores.

Mozilla's much-talked about super-priced hardware makes the OS an ambitious effort. However, presuming that the new platform will shake up the existing smartphone ecosystem post its debut would be farfetched even though the OS has a lot of potential

More details about the Firefox OS are set to arrive in the future.
