Although excellent in concept, if you delete cookies at the end of your browsing session, Ghostery loses record of *all* the tracking you want to block. Which I describe as a fatal flaw, because cookie removal is one of the basic things that you would expect a privacy-conscious user to do.

Seems like a bizarre thing for the devs to miss. I mean, who else would use Ghostery?

Otherwise, if you don't clear your cookies, Ghostery is an excellent tool that seems to do everything it promises, quickly and tidily.
