I believe uBlock Origin may allow that, if you set a pattern in it to remove those ads it can work. Generally an ad should not be intrusive like that on FA and needs to be reported.

It blocked it, so now I just use ABP and UBlock.

Yeah, i've noticed that one today, on a computer i hadn't used in a while that was still using adblock plus, switching to ublock fixed that.

Just added it. Finally works nicely :3

Try https://adblockplus.org/ which removes ads from all pages and some people even see a benefit to YouTube ads. (Not sponsored ads inside the clip sadly).

However, it will block furry artists' ads that advertise on Furaffinity and paid for those ads.

You might want to contact Dragoneer about this, as I didn't think FA allowed popup ads, only Google Doubleclick, and user ads. If not, he will have to review the ad package with that ad in it. If you can somehow get the url the ad goes to (by hovering over it, I believe, on PC, hard to do on mobile) would help. He had to do that when the old porn ad debacle happened.

I would at least report this ad. It sounds like one that might be more malicious in nature.

He is fixing it.

A script was enabled when it shouldn't have been.

If on Brave mobile, you set your adblocking setting on Fur to aggressive then turn off the block scripts. This gets rid of the stupid fuzziness while keeping ads away
