adobe has a working 64bit flash plugin for firefox3. I don't know if it is
compatible with firefox2. Right now Java is the real pain for 64bit Linux and
I am moving back to 32 bit for a few more months to let those problems settle

If you have less than 2GB of ram don't use 64bit. I haven't seen a crankier
linux box than my current 64bit quad core with only 1GB. The 32bit dual core
has 4GB and runs great except for issues with the mtrrs, but I haven't moved
to a kernel version that includes the bugfix yet. However, the few times I
have attempted 64bit on the dual core the performance difference is
noticeable, about 25% to 30% percent faster build times, but no Java plugin
is a real party crasher.
Just some experiences that I have had you millage may/probably will vary.
