I'm running Mandrake Cooker. Since it's a development version, things 
can crash here :)
I tried Mozilla Firefox downloaded from www.mozilla.org - it doesn't 
crash, but freezes instead.

Yes, I didn't figure out much.

Basically it doesn't install for me when I use /cgi-bin/moznxdemo.pl - 
it says to look into the log (but doesn't give a clue about where that 
log is).

So I installed this plugin by pointing at moznx.xpi file directly - 
after installing in this way, I could see the plugin when I did 
about:plugins.

Yes there is if I use www.mozilla.org version of Mozilla Firefox:

I had to install moznx.xpi manually by pointing a browser to that file; 
so there was a file in ~/.mozilla/plugins/libnpmoznx.so

I did:

# ldd libnpmoznx.so
         linux-gate.so.1 =>  (0xffffe000)
         libexpat.so.0 => /usr/lib/libexpat.so.0 (0xb7f6a000)

         /lib/ld-linux.so.2 (0x80000000)

but I don't know what it means :)
