My website works on Chrome, not working in FF

Ever since I upgraded to Firefox 68, several trusted websites have stopped loading; instead I get sent to an error page with:

Your connection is not secure

The website tried to negotiate an inadequate level of security.

<https://golmart.com.vn> uses security technology that is outdated and vulnerable to attack. An attacker could easily reveal information which you thought to be safe. The website administrator will need to fix the server first before you can visit the site.

Error code: NS_ERROR_NET_INADEQUATE_SECURITY

I have no issues accessing the specific website that you have included.

My first recommendation is to try running Firefox in Safe Mode to see if the issue still exists. If it works fine in Safe Mode, your security software or a browser extension is the likely cause.

If that doesn't help, try going to the about:config Configuration Editor for Firefox and change the network.http.spdy.enabled.http2 back to it's default value of true. Then restart your computer.

Hope this helps.

As a footnote, the site has an A+ on the following test, so if it's not an issue with your settings, maybe there is a "man in the middle" of your connection?
