Rated 4 out of 5 stars

I think Jackpack can really boost up add on development and get firefox more and more support, the idea is great.

Well, I install this addon for the first time today, but everytime i try the tutorial code it throw exception from _getLocalFeed, in summary I can do nothing for my first try, very bad beginning :( .
This cost I star deduct.

This review is for a previous version of the add-on (0.1.6).
