I have checked, and successfully pinged, yahoo.com from the Terminal window.
This means: ping yahoo.com was successfully returning timing results, 
also means
that yahoo.com was successfully DNS resolved into an IP address.

Since Firefox failed to work using the FQDN in the URL, I suspected that 
the DNS
resolver was not resolving in this application, so,  I obtained the IP 
address of
fedoraproject.org via nslookup, and placed the IP address into the 
Firefox URL,
and it worked.

So, I checked /etc/resolv.conf and discovered, that there was a DNS IP 
address
that was not working (ie, the DNS system was returning bad results, so I 
removed
it), now, at this point, yum is now working. HooBoy.

Sorry for posting all of this, as it turns out, it was my fault, not F10.
