Rated 5 out of 5 stars

One of the first addons I install on every Firefox. Creates a clean FF interface and makes accessing bookmarks, web info, tools, ... super convenient. It truly is an addon that considers the user and empowers them. This easily has to be one of the top 5 addons of all times. And the developer is very nice.

This review is for a previous version of the add-on (0.7.20.1-signed).  This user has other reviews of this add-on.
