JSON

Some Arabic and Indic vowel marker characters can be combined with Latin
characters in a domain name to eclipse the non-Latin character with some
font sets on the addressbar. The non-Latin character will not be visible to
most viewers. This allows for domain spoofing attacks because these
combined domain names do not display as punycode. This vulnerability
affects Firefox < 57.
