I love my Green Cats! Rated 5 out of 5 stars

Thank you so much for updating this theme for 4.0. I was distressed when I upgraded firefox a few days ago and lost my favorite theme, so I was thrilled when I came back today and discovered you had updated, and you even added a few new little features, like the nice icon for Ad Block Plus.
This is a nice clean, cute, friendly theme with a lovely shade of green -- not too loud -- sweet when I look at the menu bars, but not distracting when I'm reading a webpage. And I do like my cats! :-)

This review is for a previous version of the add-on (5.5.0).
