The Never Consent alone makes this essential, as it just works in a way certain other 'set default cookie settings' addons don't.

Ghostery is the best anti-tracking add-on available and should be used even if you also use a dedicated Adblocker (you can either disable the ad-blocking part of Ghostery, or still keep it on for more comprehensive coverage).

The UI is second-to-none, but when first installing it would help if there is a clearer indication that Ghostery has a Settings menu. There are actually useful options in there to take greater control over what type or specific trackers are and are not allowed, but this can be overlooked if you just do a quick set-up and only press the Extension icon when you need to whitelist a site.

When hovering over the Trust Site, Pause Ghostery and especially Restrict Site, adding a highlight colour or a text glow effect would improve the contrast and accessibility for some users/lighting conditions.
