Rated 4 out of 5 stars

It's a great addon, Does exactly what it promises.

Only one thing:
make the statusbar icon less wide:
check the screenshot: http://img713.imageshack.us/img713/7651/picie.jpg
Now, it has some useless extra space on it's right
- I have it in red rectangle in my screenshot -
(as you see, I have the '"enable ghost count' option unticked)

PS. I've noticed it while moving the Ghostery status icon to the left, using the Organize Status Bar addon.
(I use firerfox 3.6.13)

This review is for a previous version of the add-on (2.4.2).
