Announcing the Firefox OS Developer Preview Phone!

Firefox OS is a new mobile operating system built entirely using open web standards. In Firefox OS, HTML5 apps can do “phone things” – they can make the phone vibrate, make a phone call or send a text message.

This week we are announcing our new Firefox OS developer preview phones because we believe that developers will help bring the power of the web to mobile. These developer phones are being developed by Geeksphone in partnership with Telefonica. We are looking to make them available in February.

Updated: Added the two phone models and their specifications below.

Developer preview phones will help make the mobile web more accessible to more people. Developers are critical to the web and to Mozilla’s mission to make the web accessible to everyone. Hundreds of millions of people worldwide use Firefox to discover, experience and connect to the Web. A web based on open standards and open technologies. We couldn’t have done this without web developers. Now we are working on bringing the power of the web to mobile, through Firefox OS, along with all the power of open standards and an open community, and once again, we’d like to invite web developers to join us.

Firefox OS App Days

We’d also like to invite you to participate in Firefox OS App Days, a worldwide set of 20+ hack days happening this week. At each App Day event, you’ll have the opportunity to learn, hack, share and celebrate Firefox OS, Mozilla’s open source operating system for the mobile web. Technologists and developers from the Mozilla community will present tools and technology built to extend and support the Web platform, including mobile Web APIs to access device hardware features such as the accelerometer.

If you can’t get to an App Day, you can still sign up for Firefox Apps & Hacks, our email newsletter for Firefox OS app developers. We’ll let you know as soon as the phones are available from Geeksphone.

Try out Firefox OS

If you’re a developer interested in web technologies and mobile, now is the time to try out Firefox OS. Come learn how easy it is to create an app based on HTML that has access to all of the APIs on your device. Using the same web technologies you are used to, you can make your app give alerts by vibrating the phone, take a picture with the camera or more. Play with it, experiment, try out your website, create an app.

You can create an app for Firefox OS by making some small changes to your existing website.

You can try out Firefox OS and your app (if you created one) in several different ways:

  • Install Marketplace for Android on your Android phone. (Your friends and family can also do this – it’s as easy as installing an app, so they can try out your app too.)
  • Use the browser-based Firefox OS Simulator to view and test your mobile app on the desktop.
  • Install Firefox OS on your own hardware.
  • Purchase a Firefox OS Developer Preview device! Working with Geeksphone and Telefonica we’ve created a Firefox OS Developer Preview phone especially for developers. Be the first to show off Firefox OS and your app! First phones will be available in February.

Why develop an app for Firefox OS?

  • Keep the web open. Support the open web and help make sure the power of the web is available to everyone – even on mobile devices.
  • Simplicity. Develop on a single technology stack (HTML5/CSS/JavaScript/new WebAPIs) and deliver across the web and devices.
  • Freedom. You’re not locked in to a vendor-controlled ecosystem. You can distribute your app through the Firefox Marketplace, your own website, or any other store based on Mozilla’s open app store technology.

If you have any more questions, please read the Firefox OS FAQ.

    Second Suggestion,

    Your OS may be ultimatum!! but there is no reason that , world should use firefox operating system(Yours OS may be overide by Android next version after your release/ Apple’s next idea to your idea).
    To take sudden change and diversion in Smartphone areas, explore and work more on good chemicals and formula which will give good battery back. Give that patent to your Open Source devices and vendors.

    Do it! Do it! Do it!
    I am a Mac-user since 1987 (it was the the Mac II for the cost of a small car).
    At that time it was definitly the real thing.
    But as you know – it deterrioated structurally.
    A Mobilephone with a open system – analogous to the Firefox-browser with the plug-ins – would be a blessing for us freethinking people.

    Would it be correct to assume that given Mozilla is a non-profit organization, that the phones will be cheaper due to no need for profit other than for Geeksphone and Telefonica?

      Mozilla won’t be selling the pones, we are developing the mobile operating system. Pricing will be decided by the different operators selling phones with Firefox OS.

    I’m suspecting (hoping) we might hear more about the Keon/Peak during the Mobile World Congress:

    Anybody with an IQ larger than their shoe size MUST realise that IOS and ANDROID are NSA CIA NWO Tracking OS devices. You can’t make this sh1t up! Android devices know your exact location 24/7 so that if President ‘ODingo’ signs another executive order he can put a hellfire missile up your hind-end. ABANDON SUCH SPY WARE riddled homing devices and go with Ubuntu or Firefox, as yet not poisoned by MARXIST NWO ‘elite’ scum…

      By it’s nature any cellphone can be tracked by the NSA, CIA, dont know wtf a NWO is. Anything that has a radio transmit can be “foxhunted” and that technology existed since early radios. These days cellphones ID themselves on cell networks with traceable serial numbers and your close proximity to any tower makes it easy for operators to figure out your location. According to law your phone is not listened to, the network you connect through is. No matter what phone OS you have some calls can be intercepted by governments.

      If you really hate the idea of being tracked I’d suggest not using a phone ever again.

    February 24th, 2013 at 14:58

    1. Robert Nyman [Editor]

      The developer preview phones aren’t meant to be seen as consumer phones. The OS will be updated, but at this time we can’t promise at what interval that will happen.

    Some sources suggest the Keon might retail between $100 and $150.

    You do realise that Android is Linux based right? That’s how it’s open sourced and so customisable? Android pretty much is Ubuntu based? Anyone with the IQ higher than there shoe size would know that??
