Hi Comodo,
I want suggest (if possible) to enable by default the Firefox settings to show punny code.
Visiting on secure shopping the website: https://www.аррӏе.com/ you will see www.apple.com
I think is very bad that Firefox do not set to show punycode code by default or use another way to protect users.
The punycode code option can be enabled by digiting → about:config on the address bar than search for show_punycode two click for enable it.
