As far as I know, you will have to disable this by using a hex editor 
on the netscape executable.  There's a good tutorial (by Carole 
Leita, I think) on doing this at

You can use Fortres or StopLight or something like them to protect 
all files and directories on the hard drive.  

You can also use IKIOSK to disable all menus, buttons, etc., that 
permit saving files to disk.  You also need to check all the file 
associations in Netscape's Helpers window, because some helper apps 
may make provisions for saving files as well.  

Hyper Technologies also has a product called WinSelect, but I haven't 
tried it yet.  It may also do what you need.
