Without being logged on to Facebook, I’ve opened https://www.facebook.com/Giornalettismo in a private window. Shields doesn’t block anything, but the page is blocked: no scrollbars, no notices from FB.
I’ve noticed it depends on @fanboynz Annoyances List in brave://adblock: if I turn that list off, the pages start to work properly.
