Mozilla Jetpack 0.3 slides in
Mozilla's Jetpack project was updated over the weekend to version 0.3, improving on a number of key features. Jetpack is Mozilla's vision for a next generation add-on technology - add-ons are very important to Mozilla with over a billion total installs.
From my vantage point the biggest change in Jetpack 0.3 are the improvements to the SlideBar. Basically SlideBar is Mozilla's Jetpack term for a browser side bar.
