[K12OSN] Only Konqueror Works

[Mark Trimble]

I'm perplexed by a problem I'm encountering in K12LTSP fc6. Konqueror
browses the web without a problem with its proxy settings set to
"Direct Connection to Internet", while Mozilla Firefox fails to
function with the same setting. If I change Firefox's proxy settings
to "Automatic Discovery of Proxy", it will usually load Google, but
nothing else afterwards. Changing "System:Preferences:Network Proxy"
from Direct to Manual or Automatic doesn't appear to make a
difference.

Yum isn't successful connecting to the Internet either.

Why would Konqueror work, but nothing else?

Regards,
Mark
