This plugins allows you to track approved, pending and spam comments count from a Firefox bookmark.
Using Firefox 2+ Microsummaries (http://wiki.mozilla.org/Microsummaries), this plugin only displays the amount of * Approved * Pending * Spam comments that you have on your WordPress blog.
The bookmark will appear as
A: xx - P: xx - S: xx where you stored it.
This makes the approval of pending comments much easier.
