Yes. On my iPad when on fanpop. And it opens the App Store. I cannot use the back button to return to fanpop. Clearing history and website 饼干 helps but only for 5-10 分钟 at the most. I've decided to try private browsing to see if it makes any difference. So far so good. But then I tend to only get the advertising when I'm looking at 民意调查 so that will be the real test.
