A couple of weeks ago, the creative minds behind Mozilla Labs have launched the open source project Jetpack to the FireFox community.
Jetpack is an API which enables designers and developers to write add-ons using HTML, CSS and Javascript, encouraging more and more developers to join the 8,000+ people strong add-on community.
The Mozilla Labs Jetpack website already has a wealth of information, from guidelines to tutorials (ranging from how to disable <embed>’s or how to integrate the twitter API) and information on distributing your new add-on.
If you would like to find out more, just head over to Jetpack.mozillalabs.com for more information.
