Came across Ghostery professionally earlier this month, seems to be quite primitive in it's detection which surprised me. A site I knew to have tracking on didn't get picked up due, as far as I could see, a change in the filename of the tracking .js file. I was expecting it to track domains in a similar way to AdBlock.
