Works fine! Rated 5 out of 5 stars

Didn't work on (v.16.0a1 (2012-07-15));One hour later the developer wrote me a mail with a bugfix - is this possible? yeah it is! damn great - thank you!

This review is for a previous version of the add-on (2.1.1.1-signed). 

Already fixed!

But waiting on approval from Mozilla. Try version 2.1.2 — and update your review ;-):
