Unfortunately, the add-on breaks some sites, preventing their links from working. This occurs even when the site is added to the whitelist. In order to use the broken sites, I had to restart FF with this add-on disabled. This is unacceptable behavior.

The privacy rating could really do with more information as on the vast majority of websites there are many "unknowns" even for the big websites.Seems to have no effect on YouTube or Google.Otherwise helps with privacy on some websites & works on Firefox Quantum (Linux)

The ToS Privacy data that feeds the ranking system is not maintained at all. So most sites show a B+ rating even though they are not to be trusted at all. Very misleading.

Excellent tool to track the trackers!

A must have privacy apps... Keep it up guys!

Selbst auf seriösen Seiten denen ich vertraue gibt es acht Tracker zu blockieren?! (Davon allein fünf von google) Entschuldigt mich, ich geh das jetzt bei allein Rechnern in meiner Familie installieren

Generally great but it did prevent me from signing up to a newsletter on https://pegasys.tech/. I had to selectively disable all my add-ons to work out which one was at fault.
