Rated 3 out of 5 stars

The add-on works as advertised, but the literature says there is a Not Junk button for Thunderbird which is really the only button I am looking for. It isn't in the list of available buttons under customize. Is this button still there and if so, where?

This review is for a previous version of the add-on (1.0.2.1-signed.1-signed). 

That is an over sight on my part, I should remove it from the description. The button was removed, because Thunderbird added a "Junk" button that acts as a toggle, so it made the button redundant.
