Hi Richard,

Potentially zero difference - until the 32 bit browser just isn't there any
more / isn't patched. This is the sort of question that the debian-cd team
are also pondering: as the years go on, it is harder and harder to justify
32 bit software at least for the x86 architecture. There are already
problems with some software that just won't build well in a 32 bit
environment.
