Authenticity verification
I just updated the Firefox browser and installed it successfully. When I tried to open the browser, I got a msg stating that the security of the page I am trying to open has not been verfied. Really don't understand that since it is the firefox browser and this came from Mozilla. How do I correct that?

The System Details shows that you use a very old Firefox 72.0.2 version and not the 115.7.0 ESR version that is the last for your OS.
MacOS users on OS X 10.12/10.13/10.14 been moved to the 115 ESR update channel since your macOS X 10.14 platform no longer is supported (distributionID: mozilla-mac-eol-esr115), current releases require macOS 10.15 as a minimum.
