Didn't even notice this extension stopped working when it became paywalled with a subscription, because AdBlocker Ultimate was apparently already blocking sponsored pins/ads and video pins and doesn't leave empty spaces (still free unless you want to donate btw). I only noticed when I tried to change settings and was asked to login and pay. Not cool. Felt like a bait-and-switch.

2 stars because it does have a few Pinterest-specific features general blockers don't have.
