Rated 4 out of 5 stars
With every update something I like about this theme changes into something I don't. First firefox button changed, I installed the recommended userstyle, and it was OK. But with version 4 the texts are smaller and buttons are closer to each other which makes navigation toolbar look crowded.
I'm going to stick with 3.1 till an update is required. But still this theme deserves nothing less than 4 stars.
PS. Also, IMO a short changelog would be appreciated with updates.
