[Haifux] Running 32 bit applications (Firefox?) on 64 bit machines

Thank you all for your answers.
I suppose the conclusion is that using 32 bits for application is a nice
workaround for applications that cause trouble as 64 bits, unless it's
really computation intensive (simulations etc.). Maintaining the
necessary 32 bit libraries is a not fun, but nothing compared to waiting
for this and that binary plugin to work correctly.
Since the performance issue was mentioned more than once, I'll say that
my hunch is that except for real number crunchers (finite elements
simulations, video encoding and stuff Orna plays around with) most
applications are limited by data starvation (cache misses), so the extra
registers allowed for in x86_64 aren't necessary making any real
difference. In particular when it comes to browsers, word processors,
maybe even video rendering and compilation. But this is really just a hunch.
So 32 bit for Firefox it is. As for the rest, well, who cares, as long
as it works.
