In my case a comment box doesn't appear at all. I also don't have Firefox containers enabled. uBlock is blocking google-analytics.com and facebook.net domains only on that page, while Firefox's own tracker blocking is not accepting 3rd-party cookies from disqus, fb and google.

Although these days I'm aware that most large tracking companies are probably going beyond just 3rd party cookies and building shadow profiles based on device fingerprinting which as it stands is effectively impossible to avoid without crippling modern browsers.
