Firefox 4 general release schedule is only after the Fedora 14 release and hence it won't be in the official repository. Tom Callaway has a repository available for Fedora 14 users that has the latest snapshot however. Download and place it in /etc/yum.repos.d.

Use PackageKit or run the following command,

yum install firefox4
