Rated 4 out of 5 stars

I would give a five star, but I am experiencing a big problem on FF 6. The problem is that when some tabs are not loaded, Showcase thumbnails size and alignment are totally broken. This is a serious problem for me, because on Firefox 6, Panorama doesn't load all the tabs when you start Firefox. I also use BarTab light, to prevent my pinned tabs from loading, thus making Showcase functionality very deficient. I gave a 4 because it is an awesome extension. Will be perfect if this problem is fixed.

This review is for a previous version of the add-on (0.9.5.6).
