Userscripts.org straps on a (Mozilla) Jetpack

While it's barely been available to the public for a week, Mozilla's Jetpack project is already starting to take off. The collection of scripts as already grown from two simple demos to more than 20. Clearly developers are excited about the ease and speed with which Jetpack addons can be created.

Why, they're a lot like Userscripts - which may have something to do with a new page on Userscripts.org. In addition to "power-ups" that run in Firefox with Greasemonkey, you can download a growing number of Jetpack customizations from the popular site.

Most of the scripts are fairly basic at this point - a YouTube downloader, GMail checker, etc. - but this early enthusiasm is a good indication that Jetpack is going to be a big hit for Mozilla.

Let's hear it for add-on functionality without bothersome browser restarts!
