perfect for the throbber Rated 5 out of 5 stars

I'm a skinner and I find the APNG Edit addon perfect for my customized Activity Indicators on Firefox
from now on I can use the APNG format for my "busy" animated throbbers (instead of .gif have a look here: http://www.wincustomize.com/skins.aspx?skinid=970&libid=18 )
