Works amazing; not a single problem. Honestly, the ad-blocking is not even the best part of the add-on: it automatically deals with websites' cookies! That alone saves around 26 hours of tedious clicking and unclicking each day. Thank you to the developers!

It good.

Great little tool that saves you a lot of lifetime by blocking ads.

Works well and smooth! Can recommend

Nice and simple with a cute look ;-)

Really nice that Ghostery deals with ads, so I don't have to watch them!

You need the technical knowledge to use it well but when you do it'll save your butt from the shadiest of websites.

I have a couple different anti-tracking and ad-blocking extensions installed, so I'm not always certain which one is the source of a certain feature. But Ghostery was easy to install, easy to toggle or disable if I suspect a website isn't working, and runs really smoothly on Firefox. I'd absolutely install it again if I needed to for whatever reason!
