Maybe there's something that I miss here, but the fact that the mozilla 
devs do not find necessary (or maybe they do not have the computing 
power...) to build 64bit binaries each day ( but mind that they DO build 
the 4 beta series for x86_64 ! ) has nothing to do with fedora's policy 
about 64bit apps, does it ?
