Thank you so much. I will study the example you gave me.
I reference the "nsIWebProgress" interface. However, it is not marked by "frozen". So I am very curious whether there is a frozen interface which do the similar work.
Yes, you are right. nsIWebProgressListener and nsIWebProgress are not frozen. I think they should be frozen, but that hasn't happened yet. I think you can expect little changes to occur to these interfaces, but of course since they are not frozen, I cannot promise that they will not change in the future.
And while I am studying XPCOM, I just don't know where to find the document and propriate example. Could you give me some suggestions or directions on it?
The best advice I can give you is to read examples in the Mozilla code base. Almost all of the modules under mozilla/extensions are written as add-on components. They are good examples of XPCOM components that can be optionally added or removed from a Mozilla instance.
I think you've already seen http://www.mozilla.org/projects/xpcom, but that is certainly the best resource for XPCOM documentation.

Thank you so much for your help :-)

See this example:

The nsPrefetchService hooks into Mozilla to be notified whenever a page load completes. It does extra work (prefetching documents) when page load completes. So, you should be able to use it as an example of how to determine when page load completes.
NOTE: I still do not know for sure that nsIWebProgress.DOMWindow will correspond to the DOM window you are needing.
