Rated 5 out of 5 stars

This is fantastic for developing Jetpack/Add-On SDK projects. You can just do the following as part of your build process and see your revised work immediately:
cfx xpi
wget --post-file=myjetpack.xpi http://localhost:8888/

Thanks so much for the great extension!

This review is for a previous version of the add-on (1.1.1-signed).
