Inverted smileys? Rated 3 out of 5 stars

I find this addon very useful, thank you!Unfortunately, I am getting frowny where I should be getting smiley. I had to invert the two in the configuration dialog. It would be 5 stars otherwise.
(P.S. Hey! I just noticed that even your screenshots show the inverted smileys in the configuration dialog!!)

This review is for a previous version of the add-on (1.3). 

preferences bug

Ha! Well spotted. You know, I fixed this in the source code back in February but never released that version. Pending review by the moderators, version 1.3.1 sorts out this bug. A new teaser screenshot shows the fix :-)
