It's not a Firefox problem. It's something with the printer itself. It says:

Yes, there is an Advanced button and I can "accept the risk and continue" so I will do that. It's not like I use that web interface very often. I just needed it to set up the printer and may occasionally go in there to change a setting or something. I just wish I knew how to get a "valid certificate" so I don't have to deal with the warning.

It's Firefox, Microsoft Edge, and even on my phone which has DuckDuckGo and my tablet which has Chrome... I get the same certificate error. Do I need to buy a certificate? I don't even know how to do that.
Thank you.

</p>I don't know. If you want, I can ask another to answer that.

Thank you for responding. From reading the steps in the link you sent, this will allow me to get into my printer's web interface but I will always have to ignore the warning and proceed. Am I understanding that correctly?
Thank you.
