I was browsing MacRumors, this afternoon, and as I was reading the article about Google potentially downranking iTunes links, this popped up: There was also sound that started playing when this prompt came up, but I immediately closed Safari. Does anyone know what caused this prompt? I've never seen this before. I went to my iMac and iPad, and this prompt didn't come up. I'm aware that there was a previous article, today, about the Funny or Die Steve Jobs trailer, but what would cause this prompt to come up, while viewing another article? Your help is greatly appreciated. Thanks!
