firefox.i386 in x86_64 repo

[Demond <dnjinc wowway com>]

Is there a reason the firefox.i386 and firefox-devel.i386 packages are 
in the x86_64 repo for rawhide?  They both got pulled into my system 
when  the firefox-devel package was introduced.  However, "yum remove 
firefox.i386" shows that there are no dependencies.  I was just 
wondering if this was deliberate and if they will be around for a while.

Thanks
