While using Firefox I am unable to access two of my online accounts, one for my VPN and one for my Credit Union. So I use Microsoft Edge to access these two websites with no issue. I get this security warning using Firefox: "Secure Connection Failed An error occurred during a connection to www.ftwccu.org. PR_END_OF_FILE_ERROR The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem."

You can try to disable DNS over HTTPS.
Are you using a proxy or VPN?
You can check the connection settings.
- Settings -> 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":
