If you're seeing ads while you're on a RHP site, it's probably coming from one of the ad companies by way of a nasty little cookie on your own computer. If you use AdBlock you'll find out who, but anyway it's easy enough to get rid of these things, I've just spent an afternoon doing it to 10 computers.
My cleaner of choice is Malwarebytes but there are plenty of others.
Russ has said if ads are seen by subscribers they definitely aren't coming from the site and you need to look at what's sitting on your home computer. There's nothing to be gained by switching browsers in my opinion, browsers only present the stuff that's served to them.
