PrivacyBadger adjusts what it blocks over time vs seeing it track you. It did start blocking Google Fonts for me, and I had to manually re-enable it because I wanted it.

I forget which level of blocking it was applying; some cookies it just keeps from being cross-site, it isolates them. Others it blocks entirely. You can easily adjust which it is doing for any given cookie.

I think it's true that if you have uBlock Origin you probably don't need this though, that seems likely. I don't run uBlock Origin.
