Rated 5 out of 5 stars

I have tested with 23.0a1 (2013-04-07) and it seems to work fine.
Is this info still valid? Because I rushed and complained to Moz guys and feels a bit stupid right now...

This review is for a previous version of the add-on (0.1.0b4.1-signed). 

Fortunately only warning will be shown... for now.
