Hi Fred,

Ran into this yesterday. It seems to be a delta rpm problem.
Firefox is working because it’s downloading the whole rpm, avoiding the issue.

setting 
deltarpm=0
in /etc/yum.conf is an equivalent workaround, and fixed the issue for me. 

I’d appreciate someone who knows more about how delta rpms work weighing in on what the actual issue is.
