It does work. There is a bit in the nsIClassInfo interface that indicates "this component is a singleton" but AFAIK this is not used yet, and is provided for the future. > Is there a way to notify a component that mozilla is about to shut down? > I assume that putting code like file IO that may depend on other XPCOM > services in the destructor is not a real good idea. Adding a listener to the nsIObserver interface for "xpcom-shutdown" (or from C++, NS_XPCOM_SHUTDOWN_OBSERVER_ID) should do the job. http://lxr.mozilla.org/seamonkey/search?string=xpcom-shutdown and/or http://lxr.mozilla.org/seamonkey/search?string=NS_XPCOM_SHUTDOWN_OBSERVER_ID should give you far more examples than you need :) Mark.
