That means that Netscape (aka Mozilla) runs as if you were root.
This can be a possible security hole.
suid makes programs run as they were run by their owner. So if I
have an application that is owned by user joe, and I (raider) I run it
suid joe, the process can do anything joe can do, not what raider can do.
This is used for root capabilities mostly.

uname -r will show the kernel version. For more details check the
man page for uname. This is a quite useful tool.
That is the /etc/issue.net file that is shown. It was just
explained on the list how to customize it. I mean just to edit it isn't
enough because distributions use to rewrite it at boot time. If I recall
well it's the rc.S file... don't know for sure because I have RH right
now.
