Announcing Firefox OS App Workshops

Madrid, Bogotá, Warsaw & Beyond

blaze_your_fxosFirefox OS phones will be available to consumers in several countries this summer, and they will be looking for great apps to install from Firefox Marketplace. If you know how to build mobile app experiences with HTML5 and JavaScript, we’re looking for you—especially if you’d like to develop apps in Spanish, Polish or Portuguese! If you’re fast and focused, this is the time to take first-mover advantage.

Our first three hands-on technical workshops for skilled web app developers take place in Madrid, Spain, on Saturday, April 20; in Bogotá, Colombia on Saturday, May 18; and in Warsaw, Poland on Saturday, June 1. We hope to announce more workshops in more locales later in the season.

You must apply to attend: We’ll ask you to show us your JavaScript expertise and/or past experience building web apps and working with web APIs.

Who Should Apply

We’re looking for small teams or solo developers with solid ideas and strong web development skills. If you’ve already built a successful PhoneGap, Chrome, webOS, Blackberry WebWorks app, or other open web app for mobile or desktop, we’d love to work with you on migrating your existing app or building a new one. Mozilla engineers and tech evangelists will help participants complete an app or port an existing one to the Firefox OS phone and into the Firefox Marketplace.

Please apply now if you’d like to attend any of these workshops. We’ll be reviewing applications as they come in, with a focus on our first locations. We’ll get back to you as soon as possible.


What We’ll Offer

  • A great place to hack.
  • Hands-on help from Firefox OS developers.
  • Food, drink and demos. And t-shirts, of course.
  • More code, less talk.
  • Firefox OS Developer Preview phones, really!

How to Prepare

There’s more than one way to start building Firefox apps. Here are a few resources to get you started:

    I have completed the registration for technical workshop in Madrid. Registration form has failed several times before success. I have not received any email confirmation yet; could you verify that you have received my registration using my “not published” email of this comment?

    Thanks in advance.

      Folks, There is **no confirmation email** After you submit the form, you will arrive at a landing page that says “Thank you” for your participation. We will be getting back to everyone as quickly as possible, beginning later this week. So, please don’t worry, and please don’t look for a confirmation email.

      Thanks again for your interest and support for Firefox OS. Look forward to seeing your apps!

    Hi Havi, I sent the application form weeks ago, and I suposse that I dont’t have to wait more because I have no news from you. I was excited with the possibility to be a part of this workshop, but I suposse many other people too.

    So, can I follow the workshop in another way?

    Thank you for your important contribution.

      Hi Xavi – Thank you for your comment and for your excitement about Firefox OS. My apologies, the team has fallen a little behind in replying to all the applicants as we’ve been collecting RSVPs. We regret that we can’t accept all the great developers who’ve applied for the Workshops, but hope to extend the program in upcoming quarters.

      Meantime, the best way to follow along is to start building a Firefox App using tools and resources that are all available online 24×7. Here are the resources all attendees will be working with (also described above in the post):

      Previewing Firefox version 3.0:

      Install the Simulator:

      Learn about Open Web Apps:

      Permission model/ Packaged or hosted apps

      Thank you again, and tell us how it goes as you build your app.
