This should be a web page on mozilla.org, but it would be good background material for updating the built-in help. I'll probably have this ready in a couple weeks. The original site is mine, and I'd like to retire the content from there.
This bug has been buried in the graveyard and has not been updated in over 5 years. It is probably safe to assume that it will never be fixed, so resolving as WONTFIX. [Mass-change filter: graveyard-wontfix-2014-09-24]
