Great Rated 5 out of 5 stars

Thank you very much! This is my favorite theme, and I missed it very much after upgrade to FF4. Now I'm happy.

Installed on Win 7 and Mac OS X so far - works with both.

This review is for a previous version of the add-on (1.1.5). 

Thank you for your feedback. Now I now it is working on OSX too.
