Flash Problem on SGI machine with Mozilla Browser

Hello,

I am using an SGI O2 machine 6.5 O/S, w/ a Mozilla 1.4 browser, visiting 
a site that requires a x-shockwave-flash plugin. I am taken to the 
macromedia page for the plugin but the specific plugin is not available. 
It lists a Netscape Plugin as compatible which I download and followed 
the instructions as to the installation as best I could. On completion 
it did not work, could anyone say why it did not, and what is the solution
The files untarred were :
ShockwaveFlash.class     libflashplayer.so
which were placed in /usr/freeware/mozilla/plugins

and subsequently in almost every possible plugin located Ex.
/usr/local/lib/netscape/plugins
/usr/local/lib/netscape/plugins
/var/netscape/fasttrack/plugins
/var/netscape/communicator/plugins
/usrx/local/appl/netscape/communicator-v408/plugins

Hopefully, someone can shepard me out of my miseries with this

Thanks
