I just can't think of a solution that doesn't fall into at least one of
these categories:
1) Some sort of user-confirmation that most users will not understand
(such as the dialog)
2) Uses annoying ugly UI that will make no sites want to use it
(such as a blinking red border)
3) Is unsafe
4) Will be annoying since advertisers are going to abuse it.
