Works again on Firefox 16.02 ... Rated 5 out of 5 stars
Same as user Lee_Dailey on mozillaZine forums ( http://forums.mozillazine.org/viewtopic.php?f=48&t=522643&start=450 ), "for some unknown reason the problem [expand/collapse arrowheads not working] has gone away. i have _no_ idea why!". That was the only issue I had, disappeared .. understanding why/how is beyond, beyond, far beyond !This review is for a previous version of the add-on (13.0.20120505.1-signed).
Please update for Firefox 16+ Rated 4 out of 5 stars
