Images purporting to be screenshots of Firefox's new mobile operating system have leaked, claiming to represent the final version of the OS.
Brazil will be the first country to retail Firefox-powered devices. It is not yet known whether the handsets will be available in Australia.
TechWeek Europe has posted screenshots of the upcoming OS, featuring home screen tiles instead of icons, a low-lying notifications bar, and stripped-back camera, messaging and phone apps are totally stripped back.
It appears Firefox OS will support the same "Do Not Track" private browsing feature as the Firefox desktop web browser.
The OS is aimed at “developing markets”, and designed to work smoothly on entry-level smartphone hardware.
Every phone feature – including phone calls and messaging – is an HTML5 web app, meaning a constant data connection is required.
ZTE and TCL have been announced as the first manufacturers intending to provide Firefox OS hardware, with Qualcomm Snapdragon processors on board.
