I have been using purify, but it's like 5 years old and seems to be easily detectable by anti-adblockers.

I got several as they went on sale, and am trying AdBlock Pro right now, on the theory that newer and more up to date ones will more effectively anti-anti-adblock.

I found AdGuard Pro in my extensions. Must have been on sale, as it's the pricey "no subscription" version of the product. Will try if the above doesn't work out (I expect that it will)
