Superb Addon Rated 5 out of 5 stars
Works very well.
Though would like to report a bug:
I am using this on Fedora 16 (x64) Firefox 10.
When ghostery has blocked any bugs, and I click on the icon, it appears and works as it should. But when it is not blocking anything, and I click on the icon, the panel becomes 'sticky'... that is, it remains open only if I keep my mouse clicked. The video shows this demo.
Also, when I hover over the icon (on a blocked page), I can see two overlapping boxes behind. Ideally that box should be only one.
Feature suggestion: Ghostery preferences, filter list etc. sync over Mozilla Sync / Weave
