Mozilla Jetpack, an API For Standards-Based Add-Ons

revealingheart writes "Mozilla Labs have released a prototype extension called Jetpack: An API for allowing you to write Firefox add-ons using existing 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. Example add-ons are included on the Jetpack website. While currently only a prototype, this could lead to a simpler and easier to develop add-on system, which all browsers could potentially implement."
