offline installation?

[Quercus]

Hi there... I guess this question has already been asked, but right now
it isn't in the ng...

How can I make an offline instalation? I mean, downloading the xpi files
along several days and install them after that...

I did that with windows, and now I'm trying to do the same in my linux
box.

I'm downloading the xpi files from
ftp-euuk.netscape.com/pub/netscape6/english/unix/linux22/xpi/

Any help would be great, thanks in advance.
