Is that not what you are looking for?

Yes, you're right, apologies to you and to 'gorhill.

I misunderstood before and at the time I read "Fanboy's Anti-ThirdpartySocial" as "Fanboy’s Social Blocking List" not "Anti-ThirdpartySocial (see warning inside list)", perhaps because the latter sometimes seems to change its name to "Anti-Facebook List" for reasons I haven't identified. The former does block numerous Facebook addresses, just not that one.

I'm not sure any of this really invalidates my original point, though. Two weeks ago my Firefox had a couple of privacy/blocker extensions installed, and with no real configuration beyond ticking the "everything" boxes in the Ghostery wizard, they blocked pretty much everything that bothered me. Today, with FF42, neither of them works any more.

Apparently the new version involves figuring out which of the almost 50 lists that are suggested but not active by default in uBlock Origin are needed to get a reasonable level of blocking. I dare say almost no-one is actually going to get that right reliably even if they want to. And while I might have guessed to just activate everything under the social heading to block Facebook Connect (at least if I'd realised something related to Facebook wasn't already blocked by default), I have no idea which of those lists to even check to see if I can disable the various web font resources that involve tracking.
