Recently, the Shmoo Group discovered that Firefox is vulnerable to precisely the exploit that i predicted in my 2002 paper—Ping

What happens if the character set includes the full set of non 7-bit printable ASCII characters to mimics all needed letters?

E.g., we see a totally purple "paypal" ? As nobody to date has complained about the yellow background colour of Firefox 1.0 URL bar, my guess is that this will pass by too.—Ian

Only "paypal" would have a purple background, not the entire URL bar. That would look considerably more odd than the entire URL bar background switching to light yellow for https. Why would anyone complain about Firefox’s yellow https URL bar, and why are you certain that you would have heard about it if they had?

My suggestion doesn’t help people who want to visit non-P7ASCII domains.—Mike
