“The Mozilla Foundation previously issued a patch for Firefox 1.0.6 that protected users against the IDN link buffer overflow flaw at the expense of removing support for IDNs. Firefox 1.0.7 has a more permanent solution that does not involve disabling IDN functionality and any users who installed the patch will find that IDN support is restored when they upgrade.”
