That seems strange to me, but I guess it would depend on what the filtered-out domain provides or how software on the iPad handles that missing bit. *shrugs* Surely we'll get things ironed out.In my case, I use Firefox 71.0.1 on macOS 10.14.6. I have uBlock Origin installed. I see no ads at all, not even the the large empty box I see on iPad. I have pihole serving DNS queries form a VM on FreeNAS 11.2U6 so that will only block domains not engage in filtering out unwanted elements from the html that uBlock can do. Perhaps, this may be the source of the big empty box in the iPad?
Ok, I have privacy badger also but my settings for this site are probably different than yours, I do not have it entirely disabled for these forums. The way I set it, I have no troubles with the ads, whether PB is a cause I dunno. It'd be nice if that were the common denominator instead of some sort of faulty coding (Opera).I just tried on another Mac in the office with FF 70.0.1 and there I see an ad instead of a big empty space. Biggest difference vs my Mac is that I have the Privacy Badger extension installed.
