The blocklist check hashed the hostname as the page gave it, so "myetheywallet.com." and every subdomain written that way hashed differently from the listed "myetheywallet.com" and opened approval prompts with no warning. The browser and DNS treat both spellings as one host. hostnameVariants() now drops one trailing dot before building the hostname and its parent domains, so the check sees the name the list holds.
