For example, to check the authenticity of and visit the authenticated site, add .trustedurl.org after the Top-Level Domain.
>getmonero.org.trustedurl.org
Entered into the address bar, this resolves to
>getmonero.org
You can also just type in the domain name without the TLD
>getmonero.trustedurl.org
Which similarily resolves to
>https://getmonero.org
This of course also works with the protocol
>https://getmonero.org.trustedurl.org >https://getmonero.trustedurl.org
Now say an attacker were to make a phishing site getphished.org, and you were uncertain if it were authentic. In this case, just apply the same postfix to the suspect domain
>getphished.org.trustedurl.org
Which resolves to a connection error page, because it isn't in the authentic URL whitelist.
