Rated 5 out of 5 stars

I'm getting it back. Need the information, and this add-on is the best of its category (what we need is reliable data, right?).
I call upon the author to keep this little gem on the go with upcoming versions of Firefox. I just can't stand it when most valuable add-ons disappear with time: please do keep this excellent work on :)

This review is for a previous version of the add-on (2.0.2).
