As a heads up since this might have a large effect on people.... The upstream vendor has rebased form firefox 3.6 onto firefox 10... This effects both centos5 and centos6. I'm not sure reading this whether this is the extended update support version of if they intend to follow Mozilla's new release process....guess we'll find out when firefox 11 gets released... Here's the details: http://rhn.redhat.com/errata/RHEA-2012-0327.html Regards, James
