Rated 5 out of 5 stars

It works really great and it definitely makes it easier to differentiate the sites I have open. The only thing I was wondering was that if there was a way to make it look cleaner on the Mac version when you're using the default look for Firefox? Also if there was a way to make it work with the vertical toolbar and change its color as well?

This review is for a previous version of the add-on (1.4.1-signed.1-signed).
