Hi, Together with Firefox 3.6.4 update for RHEL5, update for RHEL4 has been released. https://rhn.redhat.com/errata/RHSA-2010-0500.html Are we going to release that update for CentOS4? Within my repo I will continue to release Firefox/Thunderbird updates for Centos. But I guess this update has to be released with Centos too. David Hrbáč
