 Today I encountered an interesting issue where the cert of a website is
 valid both in chrome and firefox, but not in Tor Browser.

 The site in question is: https://ykacademi.com/registration/

 Tor Browser returns `SEC_ERROR_UNKNOWN_ISSUER` but the issuer seems to be
 valid (Godaddy). After some digging, I thought maybe the reason is that
 the cert has been issued for a different domain (www.minervalms.com) but
 it has ykacademi.com listed in its DNS names. And even if this was the
 issue, Tor Browser is returning the wrong error. But I might be completely
 wrong about why this error accrues.
