Installing 32-bit firefox is probably the easier solution, unless you're so low
on disk space that you can't afford the 32-bit libraries. You probably don't
want firefox using more than 3 GB of memory at a time anyway. We include
firefox.i386 in the x86-64 repos because many people prefer this solution.
The 64-bit kernel has a much easier time with memory management on boxes with 1
GB or more memory, so even if you're running 32-bit apps, it can still help with
performance. If you install 32-bit, and want to go 64-bit, you'll need to do a
full reinstall.
