All of these are examples of help buttons for which no help has yet been created. Most of these are mozilla-only UI, too, like the DOM Inspector pref panel and so on. ACCEPTING. We can at least put pointers to some basic help content for these in the UI (e.g, in pref-help.js, where the context keys for the pref panel are listed), even if there is as yet no specific contextual help.
I am nominating this for 1.0 since it will give users a bad message if they click help and don't receive any.
Patch for these bugs is over in 129540: http://bugzilla.mozilla.org/attachment.cgi?id=83604&action=view Where there is not help content for the panels listed here, I open the Welcome page.
These are FIXED with 145331, which sets the default topic properly when the context ID is not available.
