Hey why dont you test it yourself? I use SRWare Iron from version 4 or 5, and never had undesired behavior. Adblock in this browser is integrated in that way, that it will not send requests to blocked URLs, I was testing it many times, using Wireshark. Chrome was lacking this functionality, adblock extenstion was not working properly, until about version 7 or 8.
Even that diff from Iron version 4 convinced me, that its exactly what I want, I cant see why is everybody talking about scam. Yeah developer wants to make money from website ads, but product is perfect. People get a life.
