Comment 6 for bug 233901

So far, the only real way I've been able to find any documentation on Mozilla's
hidden preferences are by doing searches on Google or wading through the
(incompletely documented) js files themselves. As a power user, many of the
undocumented options that I have managed to dig up information on have been of
interest to me. It would be nice if I could find these all documented in one
place, either on the web or in Mozilla's help system.
