Maybe this is just adding noise, but my experience with firefox on my
x86_64 desktop convinced me to pull out the 64 bit install and replace
it and all the needed pieces with the 32 bit one.  VRVS from CERN was a
show stopper in that even with the correct JRE it never worked - not to
mention many plugins that are available only in 32 bit versions.  One
day this may all be fixed but it is not today.  I suspect running a 64
bit browser has very little real advantage.
