ok thank you it works ;-).
In a summary you register for webprogress event like this :
- register for xpcom-startup and implement observe method (of nsIObserver interface) like this :
...
NS_DEFINE_IID(kDocLoaderServiceCID, NS_DOCUMENTLOADER_SERVICE_CID);
nsCOMPtr<nsIWebProgress> progress(do_GetService(kDocLoaderServiceCID));
rs = progress->AddProgressListener((nsIWebProgressListener*)this,
nsIWebProgress::NOTIFY_STATE_DOCUMENT);
...
Be carefull : you also have to implement nsIObserver and also nsSupportsWeakReference...

Are you trying to embed gecko or write an extension? I am not sure you would use the same code in both cases.
When developing an extension, I do it the following way:
Inherit from nsIWebProgressListener and listen for document load events.
Then inside:
OnStateChange(nsIWebProgress *aWebProgress, nsIRequest *aRequest, PRUint32 aStateFlags, nsresult aStatus) {
...
nsCOMPtr<nsIDOMWindow> window; rv = aWebProgress->GetDOMWindow(getter_AddRefs(window)); if (NS_FAILED(rv)) return rv;
nsCOMPtr<nsIDOMDocument> domDoc; rv = window->GetDocument(getter_AddRefs(domDoc)); if (NS_FAILED(rv)) return rv;
nsCOMPtr<nsIDOMHTMLDocument> htmlDoc = do_QueryInterface(domDoc); if (!htmlDoc) return NS_OK;
... }
I've never tried embedding gecko so if that's what you're trying to do someone else will have to help you.
