Maybe I missed something? Rated 3 out of 5 stars

The extensions creates a huge toolbar that takes up valuable screen real estate. I was thinking it would just add a little icon to FF's existing addon bar or a button on the existing toolbar. Switched to PassIFox (no toolbar) as the 16:9 widescreen displays these days already have quite limited vertical screen space...adding more toolbars is a nonstarter.

This review is for a previous version of the add-on (1.2.3.1-signed). 

You can customise the icons to suit your preference / screen resolution:
