Mozilla is out with a new project called Jetpack, which is an API designed to make building extensions for Firefox easier and faster. It won't require extensions to be written in XUL and will allow developers to use standard technologies such as HTML, CSS and JavaScript. Notably, Jetpack will also allow Firefox users to load extensions without annoying browser restarts, and will resolve compatibility issues between older extensions and newer versions of Firefox.
