The new Firefox OS will debut on a pair of phones called the Keon and Peak. But these smart phones are meant mostly for developers.
In a post to Mozilla Hacks, company rep Stormy Peters said Firefox OS would be "built entirely using open web standards" – a kind of natural extension of the Firefox web browser, which is also open source. "Developers are critical to the web and to Mozilla’s mission to make the web accessible to everyone," Peters wrote.
Judging by the website of Spanish manufacturer Geeksphone, there will be two Firefox phones: The 3.5-inch Keon and the higher-powered 4.3-inch Peak, which Geeksphone describes as a "powerful developer preview device introducing cutting edge features."
