firefox and certificate issues

[Buck_Naked]

When attempting to go to https://arlo.netgear.com/ websight using Firefox 58.0.2, get an error message that says:

Your connection is not secure

The owner of arlo.netgear.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

When I click on advanced options, I see the following:

arlo.netgear.com uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The server might not be sending the appropriate intermediate certificates. An additional root certificate may need to be imported. Error code: SEC_ERROR_UNKNOWN_ISSUER

Anyone else having a similar issue?
