Jetpack Project: weekly update for May 14, 2013


Unless you’re hiding under a rock, you are probably aware that the Mozilla Project has released Firefox 21 today. Additionally, unless you’ve been completely ignoring my recent posts on this blog, you might also realize that Firefox 21 signals a new chapter in the life of the Jetpack project, as we ship the SDK’s module loader and APIs in Firefox 21.

To me this is a big deal, for add-on developers, for Firefox developers, for the entire project. I’d like to thank everyone involved for all the hard work, but in particular there are a few people who deserve special mention:

  • Atul Varma & Aza Raskin started Jetpack in 2009 in Mozilla Labs, then rebooted it in 2010, ushering in the modern era of content scripts, CommonJS modules the command-line cfx tool and Add-on Builder.
  • Dietrich Ayala, David Mason, Myk Melez & Brian Warner who guided the project through the ‘re-boot’ phase, always with an eye to landing Jetpack’s capabilities in Firefox and revolutionizing how Firefox features are made.
  • Dave Townsend, Irakli Gozalishvili and the rest of the current Jetpack team who have done a ton of work coordinating a series of important changes to make the SDK fit nicely into mozilla-central.
  • Various Mozilla Labs engineers including Shane Caraveo, Anant Narayanan, Andrew Sutherland & David Ascher who kicked the tires and built prototyped their own crazy ideas based on our shaky prototypes and beta releases.
  • Our fantastic contributors who keep showing up with great code for new features and bug fixes.

Now that we ship with Firefox I have decided to dial back the frequency of these posts to every 6 weeks on uplift and instead highlight for developers the new features and bug fixes that have landed in the recent Nightly cycle. As always if you have questions, feedback or want to get involved you can find us on the wiki, on the email list and of course in #jetpack on
