Other have answered about Firefox.  I'm running 64-bit Fedora 9 with a 
quad-core AMD Opteron with no problems. 32-bit apps work well, 
especially on Fedora where you have the 32-bit libraries installed in 
addition to the 64-bit libraries. I also have a 64-bit laptop that has 
been running a 64-bit Linux OS for about 5 years with no problems. 
Memory management under 64-bits is better than it is in a 32-bit OS.

A few years ago, I did perform some benchmarks and found that 32-bit 
apps generally are faster with a 64-bit OS.
