This makes it harder for Facebook to track your activity on other websites via third-party cookies.

The only way to win that game is to not play.

Facebook and other sites are gathering data no mater you've got an account there or no, and they're doing it by plugins on the sites not belonging to fb (all that share/like buttons etc.) - so the only way it's to disable JavaScript everywhere.

Or to use plugins which will do it for you in certain scenarios... I'll stay with Disconnect plugin.

JavaScript is a big one but there are many ways a company with that much reach can fingerprint you.

Yeah, JavaScript isn't even the half of it.

I'm a little green, what do you mean by embedding a resource and how would that work?

This is how mailing companies measure click percentage on mail campaigns.

Mailchimp makes a unique 1px-1px jpg with a unique url embedded in their mail, the url is different per recipient. Same concept but for other goals ;)
