netscape6 mozilla helper plugin

Hi. SuSE 7.0, kernel 2.4.7. During time I've used and configured Netscape 4.76 for things as hearing .wav's and .mid's (plugin Plugger), and seen and hearing realaudios with rp8 for Linux. Moreless, the configuration files for these things are clear (such as /etc/pluggerrc, ~/.netscape, etc). I've aditionally installed Mozilla and Netscape 6 (I understand they can coexist, and with Netscape 4.76), but it must be I am stupid enough for not not finding clear instructions to configure them, and even if filling helpers by hand it is not remembered. I would appreciate: -briefly, how to proceed; -an URL with clear instructions; -where should be the configuration files for Mozilla and Netscape 6.
