You are using a severely outdated OS and browser. Your situation may not improve. Try a different browser.
I believe Firefox has an ESR version that is still supporting Catalina.
With regards to internet security, a lot has changed in the past six or seven years since Catalina was released. If your Mac is capable, you might consider upgrading your OS to something newer that is still supported, or at least less obsolete.

This currently supported version of Firefox will run under macOS Catalina:
Firefox 153.0.1 System requirements – Firefox.com
So will this Extended Support Release:

Might this be a certificate error, due to a very old trust store?
If so, maybe the following helps?

That’s not been checked as far back as macOS 10.15, though.
