I was under the impression that a white-list including here and some other forums I'm on was working ok, I just checked it and yup, seems like waterfox looked at it, Shrugged, and refused to parse it, manually telling ad nauseum and bluehell to disable here, etc, worked.
I'd really recommend taking a moment to check yours right now, dear reader, if they are disabled, & making sure they are.
Smugly saying "but malwarez?!" is meaningless (&, Just my opinion, mind you, selfish), until you can actually point to a case of being infected by an ad/malware from here. Even then, as you should know by now, the Nexus has nothing to do with ad content.
Tl;dr : Take a couple of seconds from searching for deathclaws with breast physics and turn off addblock here.
