plugin select in mozilla/seamonkey

Hello all: How can I set mozilla/seamonkey which plugin to use for media files? I have both kaffeine starter plugin and gxine plugins installed. I want to use one of them but don't want to remove the other one. In earlier mozilla/netscape versions there were an option in preferences called Helper Application (?) where I could pair MIME types with the applicatons to handle them. Thanks, IG _______________________________________________________________________ 25% kedvezmény 3 könyv vásárlása esetén!
