I had no such thing happen to me, don't know if it's because I block everything facebook or because I disable javascript by default. Point is nowadays most websites try really hard to get in the way between visitor and content to push for some pointless marketing. Disabling javascript or at least third party javascript is the modern popup blocker. Maybe give a try to noscript or requestpolicy with firefox, no advice for opera which used to be something but now is just a skin for google chrome, speaking of which if you're using google chrome you deserve to suffer through overlays.
