Description of problem:

Yum is not seeing all the files available in the repository.

For example 

When I try to update firefox

 yum -y upgrade firefox
Loading "installonlyn" plugin
Loading "skip-broken" plugin

I get a denial for because there is no update for firefox-devel

If I just list firefox-devel, you reports that there is no available packages
for firefox-devel

 yum -y list firefox firefox-devel
