Mozilla has unveiled Jetpack, a project to make Firefox add-ons easier to code and deploy.
In a blog post, Mozilla detailed:
Specifically, Jetpack will be an exploration in using Web technologies to enhance the browser (e.g. HTML, CSS and JavaScript), with the goal of allowing anyone who can build a Web site to participate in making the Web a better place to work, communicate and play.
Most importantly, from a user perspective, Jetpack will allow new features to be added to the browser without a restart or compatibility issues, resulting in little to no disruption to the online experience.
As with all Mozilla Labs initiatives, Jetpack is an open source project and everyone is welcome to participate in its design, development & experimentation.
