Basically that says that upstream no longer thinks that Firefox is runnable
on RHEL-6/CentOS-6 anymore. I think there was a similar problem at the end
of EL-5 when a 'YOU HAVE TO UPGRADE' fix from Mozilla was released and
while a lot of work was done by Red Hat to get it to work on RHEL-5, some
items (and I really think it was sound and plugins) did not work. At the
tail end of a release, most 'desktop' concerns are very hard to figure out
as 10 year old software API's are rarely kept working by the various

I want to be clear that I do understand this is causing major issues for
users. I think a lesson learned from EL-5 and EL-6 is that EL releases need
to be clearer on the difference between desktops and servers. There seems
to be a point where desktop utilities fixes are mainly going to be
'reasonable effort' versus 'guaranteed' to be 100%... usually in the last 6
months of a release. That way users can plan better that a certain amount
of work is going to be needed by them to continue it working.
