I LikeIt! Rated 5 out of 5 stars

Love the way it saves tons of space on the tab bar. One item, though - I tried to auto-Faviconize the about:blank page and it doesn't quite work. It works on the first tab, but not multiple blank tabs. Might want to take a look at it.

This review is for a previous version of the add-on (1.0.1).
