Rated 5 out of 5 stars

wow, this is fantastic work. I used this to find out if changing the font-family of an element to something that doesn't change the font causes a MozAfterPaint event, I found out it does thanks to this addon. Showing the screenshots of the paint events is icing on the cake. Thanks so much!

This review is for a previous version of the add-on (0.1.7).
