This is what firefox tells me. Looks OK to me.

Then _blush_ - using exactly [https://www.dnssec.co.za](https://www.dnssec.co.za) gives me a certificate error.  
I guess I never type that in.

Wildcards are meant to be coming in the new year - may just live with it.

Even with wildcards, a cert for `*.example.com` won’t cover `example.com` so you would still need both if you want both to work in all browsers.
