Hot on the tail of a major update to Jetpack, Mozilla Labs is proud to announce the launch of the Jetpack Gallery. The gallery makes it easy for developers to host and promote their Firefox Jetpack add-ons, and makes it even easier for users to find those great new features. Jetpack is a Mozilla Labs project that enables anyone who knows HTML, CSS, and JavaScript to create powerful Firefox add-ons.
The Jetpack gallery, while still a beta, makes it easy to find new functionality that extends your Firefox experience with new abilities. You can browse Jetpacks by tag, author, and popularity, as well as vote on and review the ones you try. Jetpacks in the gallery have screenshots and video introductions, making it easy to get to know what you are getting before installing.
