Cant say I much disagree with him on this, the browser is doing exactly what it was desigened to do. That being said there should be a patch which give the user some indication of there that windows is from!
Opera has said that its latest browser, 8.01, would display the pop-up's origin, letting a user inspect its URL to see if it came from a trusted site.
Im a FF user myself but kudos to the good folks at operasoft..
