A comment should be added to the paragraph Making Plug-ins Scriptable in implementation example of NPP_Destroy function. Here is what I just added to the article http://mozilla.org/projects/plugins/scripting-plugins.html from where the code was actually taken: NPError NPP_Destroy (NPP instance, NPSavedData** save) { if(instance == NULL) return NPERR_INVALID_INSTANCE_ERROR; // release the scriptable object + // Note that even though we release it here it does not necesserely + // mean that its refcount will go to zero and it will be deleted. + // XPCOM code in the browser may still hold more outstanding + // references to this object and even execute calls to it at some + // later time, when other plugin objects no longer exist. So in real + // implementations some measures of precaution must be taken here to + // prevent crash such as notifying the scriptable object that there + // may be some dangling pointers and it is not safe to use them any more NS_IF_RELEASE(instance->pdata); }

moving stuff over to an outside-the-firewall email for the time being, looking for people to pick these Help and doc bugs up for me.

taking over some of Ian's bugs

XPCOM plugins are gone.
