It's truly a set it and forget extension.

automatic cookie decline is a game changer

After the initial set-up, which wasn't hard, the only thing I notice is the lack of ads getting in my face!
To get a five star review from me something has to be very close to perfect, which is what Ghostery is.

this is my default ad-blocker. working excellent for me.

I love that ghostery automatically refuses all cookies. It has made my life so much easier

I just love being able to watch youtube in the browser and do not get interrupted by ads.

Works very well

Ghostery is a must have for FB and YT users. Don't browse without it. Particularly for YT it turns an unbearable experience into a very pleasant experience. It's also meticulously maintained.

I've left one other review for an extension (Noscript). I'm not a promiscuous reviewer. Ghostery makes the cut. Kudos to the author(s)

Works very well and has been around for a very long time!
