Mozilla Announced Jetpack SDK 0.3

Mozilla announced Jetpack SDK 0.3 this week.

Jetpack is a development environment geared toward making it easier for developers to build extensions to the Mozilla platform. It's a set of extensible APIs that programmers can use to build add-ons to the open source Firefox using HTML, Cascading stylesheets and JavaScript.

Two high-level improvements in the Jetpack SDK 0.3 are "context-menu" and the "self" API.

The context-menu API lets add-ons add items to the context menu for Web pages. This gives users additional options when they context-click on elements in pages or pages themselves. For example, an add-on might add an "Edit in Pixastic" item to the context menu for images.

The self AP enables add-ons access to resources such as: Web pages, images, etc that are bundled with the add-on package. For example, an add-on could bundle an icon that displays the browser's status bar.
