You can try to disable DNS over HTTPS.
- https://support.mozilla.org/en-US/kb/firefox-dns-over-https
- https://support.mozilla.org/en-US/kb/dns-over-https-doh-faqs
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.

Please explain the problem in detail. What happens? What is/are the exact error message(s) ?
There is security software like Avast, Kaspersky, BitDefender and ESET that
intercept secure connection certificates and send their own.
