Rated 4 out of 5 stars

Love this theme, but the latest version breaks Fission progress bar extension. I had tweaked the previous version to work in FF3.5 and the Fission bar worked fine in that, but since the update it's totally messed up.

Fission author discusses theme compatibility here -> http://forums.mozillazine.org/viewtopic.php?p=2087637#p2087637 and in a few other places.
