I use Strict Tracking Protection, Facebook Container and Multi-Account Container and I am beginning to think it’s overkill. Doesn’t Strict mode block third-party cookies anyway? I also clear cookies on exit. Containers allow us to login to the same site with different identities, so I am assuming it containerises first-party cookies too, but I wouldn’t need that. Also, doesn’t Multi-Account Container replace Facebook Container if you create a separate container for Facebook?
Well yes, but I am trying to figure out if Strict Protection and different containers overlap in what they do. If yes, I don’t see why FF maintains and promotes all of them. Facebook Container seems like a single-case Multi-account Container, and Strict Protection seems to block cross-site cookies anyway.
On fingerprinting, perhaps switching languages, addons etc on/off would confuse trackers. FF could even do that automatically.
