works if you unpack it Rated 5 out of 5 stars

The addon does work if you unpack it. Since FF4 xpi files are not unpacked like they use to so now there is a guide when you need to add which the developers failed to follow -- see http://blog.mozilla.com/addons/2010/09/23/changes-to-how-extensions-are-installed-in-firefox-4/ also see https://developer.mozilla.org/en/Install_Manifests#unpack -- this addon needs to be unpacked because it uses windows bat and linux shell scripts.

This review is for a previous version of the add-on (0.3.0.20100706).
