   Entries which do not have URI_SAFE_FOR_UNTRUSTED_CONTENT will run with chrome
   privileges. This is potentially dangerous. Please use
   URI_SAFE_FOR_UNTRUSTED_CONTENT in the third argument to each map item below
   unless your about: page really needs chrome privileges. Security review is
   required before adding new map entries without
   URI_SAFE_FOR_UNTRUSTED_CONTENT.  Also note, however, that adding
   URI_SAFE_FOR_UNTRUSTED_CONTENT will allow random web sites to link to that
   URI.  Perhaps we should separate the two concepts out...
