Well done Rated 5 out of 5 stars

Excellent attention to detail, useful options for personal customization, and minimal chrome (thinner toolbars and scrollbars = more room for content [window])
@eBZ3fKft (2010-12-01): that feature is available if you right-click on the back-forward button(s).

This review is for a previous version of the add-on (3.6.4).
