I don't think it's our hosting company since it's AWS (Amazon Web Services)
afaik we're in process on getting a new C..A.
til then Firefox is still working for me. Or I guess Edge....
When there's an update the Chairman will post it here.
I love SB but not enough to use edge...
If you get the error, you can just click the button to ignore the error. It smacks of political stunt by browser manufacturers to me. It's not like they've blacklisted "joes used digital certificates and toothbrushes".
For what it's worth, a consortium of browser manufacturers has blocked the following certificate authorities.
Symantec, GeoTrust, RapidSSL, Thawte, and VeriSign
Of course, verisign is only the biggest root ca in the world.. no harm though, right?
As a website owner your only options are 1. lose traffic from chrome and ff users or 2. buy a cert from some other company and hope the eventual lawsuit takes care of it (if you even care after paying for a second cert).
Here are the details:
Distrust of Symantec TLS Certificates
It's part of a long running feud between Google and Symantec. Google has apparently successfully recruited mozilla (maybe others?) to join them.
Google is fighting with Symantec over encrypting the internet
Google's published details make it sound on the surface like their motives are altruistic....until you realize that Google owns a CA that competes with Symantec (and the others). Guess what? Google Internet Authority G2 isn't blocked anywhere

. Oh, and
as if Google has never been hacked. No business that has an internet connection has never been hacked - unless you just haven't been noticed (yet).
Children of unwed mothers, Google.
What it boils down to is that default permissions for sites who have paid someone "trusted" by google or mozilla for a certificate are more lenient than for sites who have not. This is because all a certificate does is (supposedly) identify one end of a connection. Your browser then decides to negotiate a secure connection (or not). It's entirely possible to use SSL or TLS with your own cert, or no cert at all.
This is an effort to crush their largest competitor in the certificate sales space - nothing more.

sorry
