Newbie trying to upgrade Mozilla 1.4 to 1.8a -- Not succeeding!

[Todd Nelson]

Hello from Malaysia,

I'm brand new with Linux (Fedora Core 1) but a long-time user of 
Netscape. I'm trying to upgrade the Mozilla 1.4 that came with my Fedora 
distro to 1.8a. Being new at Linux, I've searched the Forum and tried 
what I found for advice but it's not working for me. I can't seem to 
uninstall 1.4 (which is recommended by Mozilla's release notes) using 
rpm and -e and -Uvh; and the installer won't create a new directory for 
me to install in (usr/local/mozilla). When I tried using the command 
line, it said I didn't have permission to create "mozilla" in the 
usr/local directory. I am the root and know the password, so ...?

Any help would be appreciated.
