Rated 4 out of 5 stars

I've found an unofficial fix for the icon size problem here:

Works nicely.
Hope this will be integrated soon.

Its button (icon) size doesn't seem to fit to the toolbar or tab-bar (too big) when I'm using it with small icons on my Mac version of firefox 4.
Otherwise it works perfectly.
