2006 June 18 17:00:00: Links below are dead. There is an IP address (22.214.171.124) for “developer.netscape.com” but there is no http server there. Here is a page in the same format as what the Wayback machine remembers for “http://developer.netscape.com/docs/manuals/communicator/jsref/index.html?content=navig.htm TARGET="_top"”. The higher level pages seem gone, or I just can't find them with Google. Maybe developer.netscape.com will be up tomorrow.
Having skimmed the Predefined Core Objects and Functions, they all seem to be convenience or utility objects. I think they do nothing that the programmer could not do otherwise.
What are signed scripts about?
