I would fix perhaps by the new web browser doing: - Document scripts are restricted, and can be customized and spoofed (or fully disabled) by the user. - Whether or not a link can be opened, and whether or not it is asked, depends on user settings. If it is configured to ask, it does so for both known and unknown URI schemes. - Known and unknown schemes are both considered different origins; they do not redirect to about:blank (unless it is a scheme which is handled by rendering a document, which happens to redirect to about:blank, but it does not normally do this). - Scripts cannot detect such prompts, and only one can be displayed at a time. One key combination can be used to prevent further prompts; even if a way is found, only one will work anyways. And many other improvements, because existing web browsers are bad in a lot of ways.
