Works great! I can now see Flash! I put the 32 bit Firefox in
/usr/bin32/firefox . The Mozilla site had a gz instead of an rpm, so
untarred it in /usr/bin32/firefox. On the Flash installer script, I just
commented out the exit in the architecture check, so the script continued
on instead of exiting on finding the 64 bit architecture.
Thanks!
