Rpmfusion, can't setup repos

[Jim]

FC10 i386

Trying setup Repos for rpmfusion, get errors;
Run this rpm

su -c 'rpm -Uvh 
http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm 
http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'

I get this error message;

curl (6) Couldn't resolve host 'download 1 , rpmfusion.org'

If I run in Firefox  download1.rpmfusion.org/free/fedora/ , I can get to 
website .

This probly tells me it can't resolve localhost, how would I fix that.
I'm also having some problems getting some websites in Firefox.
