Lewis -- I suggest using 32-bit firefox. This can be downloaded from http://fedora.linux.duke.edu/fedorax86_64/fedora.us/2/x86_64/RPMS.stable/ in 32-bit and 64-bit forms. I also suggest looking at the help page http://www.linuxtx.org/amd64faq.html written by Justin Forbes and his postings here. -- Phil
