The Mozilla foundation has announced the availability of a new research project called "Jetpack". It's an attempt to change how browser extensions work and make things easier for both developers and consumers.
Although browser extensions have long been one of Firefox's central features, they're only now starting to infiltrate other browsers. They're little add-on bits of code that do things, like control a music player, display a weather forecast or interact with the web in other ways.
It's also easier for the user, because Jetpack will allow extensions to be installed without the browser restart that the process normally requires.
Jetpack, like most things that Mozilla births, is open-source and the foundation is welcoming people who want to participate in its development.
