Rated 3 out of 5 stars

Works well but I lost it from the add-on bar and couldn't get it back until I edited "prefs.js" in the Firefox profile directory. Before I figured out how to re-materialize the RefControl icon, I send an email to the developer which immediately bounced (not good) and there's no other way to contact him.

Could be a great add-on if developer support was taken seriously.

This review is for a previous version of the add-on (0.8.15).
