Twitter is a world renown website, why the hell it's not loading and why I don't have the option to trust it anyway? Upgraded to version 69.0.2 yesterday and this started happening.

The certificate is issued by dnsbl, so if that does ring a bell then check out his software.

  • Issuer: C=CA, ST=ST_DNSBL, L=LN_DNSBL, O=ON_DNSBL, OU=OU_DNSBL, CN=CN_DNSBL, emailAddress=dnsbl@example.com

You can check the connection settings.

  • Options/Preferences -> General -> Network: Connection -> Settings

If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.

See "Firefox connection settings":

So cor-el, are you saying DNSBL issued the certificate? I do have DNSBL as a part of my firewall defense. I have also had no proxy in Firefox network connection.
