DESCRIPTION
My talk on Mozilla Labs' Jetpack project at the Boston JavaScript meetup: Project Jetpack is Mozilla's recent initiative to explore new ways to make extending the browser easier. Jetpack lets web developers and browser hackers alike use the open web stack of HTML/CSS/JS to modify the Firefox browser itself. Come see Jetpack in action and learn about recent developments in the project from mitcho, a Mozilla Jetpack Ambassador right here in the Boston area.

1. produce full XPI’s and submit to AMO
2. adoption of Common JS
• require module system
• add and share capabilities
3. better tools
• built-in memory tracker, unit tests
