i don't use netscape 6, but i'm sure they are using the same bookmark file and you can simply overwrite the files in netscape 6 directory with the one from netscape 4.78... if that does not work, you can always go to bookmark > manage bookmark > file > import bookmark, and import your old bookmark file from there....
on a side note, i actually suggest you use mozilla instead of netscape 6, since ns6 == mozilla + aol junks
but of course that's just my (and many other people's) opinion....
