IDND 1.4

IDND is a Firefox extension that puts a little flag in the status bar that tells you whether you are visiting a Traditional Domain Name (green TDN) or an International Domain Name (UN-blue IDN).

IDNs can be used for phishing or spoofing, so suspicious IDNs cause an optional alert box to appear further warning you to take care. This is in no way sufficient protection against all kinds of spoofing, but does add to your browsers defences.

In the status bar a green or blue flag shows whether the current page has a traditional (A-Z 0-9 -) or an international domain name. In this way you have more protection against homograph attacks.
