Good evening,
(Jon suggested)
Look here:
https://linuxconfig.org/how-to-install-adobe-flash-player-on-fedora-linux...
The web site that Jon pointed me to is a bit dated. But if "yum" is
replaced with "dnf", it works. The National Weather Service RADAR loops
now work.
I thank everyone that tried to help. I'm marking this issue solved.
Bill.
