...to access this service, use: 743 nsimessagesender message senders enable clients to send asynchronous messages to a single "other side".
... 993 nsisyncmessagesender message "senders" have a single "other side" to which messages are sent.

nsIProcessScriptLoader
if this function is called on a chromemessagesender: it will load the process script only into this chromemessagesender's child process aallowdelayedload should always be true.
... it's possible that the child process for this chromemessagesender is not yet available at the time of the loadprocessscript() call, and if you pass false in this situation, your process script won't be loaded.
... if you are calling loadprocessscript() on a chromemessagesender, you should always pass true here.

nsIContentFrameMessageManager
idl file: mozilla-central/source/dom/base/nsimessagemanager.idl inherits from: nsisyncmessagesender this interface provides the environment for scripts that are loaded into content frames using the nsiframescriptloader interface.
... frame scripts can send either synchronous or asynchronous messages to the chrome process: for details on these messaging apis see the documentation for the nsicontentframemessagemanager's parent classes nsisyncmessagesender and nsimessagesender.

nsIFrameMessageManager
you should use nsimessagelistenermanager or nsimessagesender instead.
