Re: Blocking FB cookies
Privacy Badger is not as good as people think.
Deleting cookies after you leave a site is pointless - it tracks you whilst you're browsing and, these days, people are wise to their being deleted on browser close, so they track them each time you switch tab or load a new site.
So 'self destructing cookies' and similar are a waste of time.
Block them before they even reach the browser!
Use uMatrix, NoScript + uBlock Origin or (my preferred option) adNauseum.
