A group of researchers in France and Japan say RequestPolicyContinued and NoScript have the toughest policies, while Ghostery and uBlock Origin offer good blocking performance and a better user experience.

The study also gave a nod to the EFF’s Privacy Badger, which uses heuristics rather than block lists, but once trained is nearly as good as Ghostery or uBlock, demonstrating that its heuristics are reliable.
