Utilise le channel http plutot.

Merci, c'est ce que j'ai fait. Pour ceux qui cherchent :

// Create a IO service
nsCOMPtr<nsIIOService> ioServ = do_GetService("@mozilla.org/network/io-service;1");
// Get (char*) url
nsEmbedCString uriString(url.c_str());
// Create a new URI
nsCOMPtr<nsIURI> uri;
rv = ioServ->NewURI(uriString, nsnull, nsnull, getter_AddRefs(uri));
NS_ENSURE_SUCCESS(rv, rv); 
// Create a new channel
nsCOMPtr<nsIChannel> channel;
rv = ioServ->NewChannel(uriString, nsnull, nsnull, getter_AddRefs(channel));
NS_ENSURE_SUCCESS(rv, rv); 
// Create a listener
nsCOMPtr<nsIStreamListener> listener = new MyListener();
rv = channel->AsyncOpen(listener, nsnull);
NS_ENSURE_SUCCESS(rv, rv);

///

class MyListener : public nsIStreamListener
{
public:
    NS_DECL_ISUPPORTS
    NS_DECL_NSIREQUESTOBSERVER
    NS_DECL_NSISTREAMLISTENER

    MyListener() { }
    virtual ~MyListener() {}
};

NS_IMPL_ISUPPORTS2(MyListener,
                   nsIRequestObserver,
                   nsIStreamListener)

NS_IMETHODIMP
MyListener::OnStartRequest(nsIRequest *req, nsISupports *ctxt)
{
    printf(">>> OnStartRequest\n");
    return NS_OK;
}

 NS_IMETHODIMP
 MyListener::OnStopRequest(nsIRequest *req, nsISupports *ctxt, nsresult status)
 {
    printf(">>> OnStopRequest status=%x\n", status);
    gKeepRunning = PR_FALSE;
    return NS_OK;
 }

 NS_IMETHODIMP
 MyListener::OnDataAvailable(nsIRequest *req, nsISupports *ctxt,
                            nsIInputStream *stream,
                            PRUint32 offset, PRUint32 count)
 {
 
    printf(">>> OnDataAvailable [count=%u]\n", count);

    char buf[256];
    nsresult rv;
    PRUint32 bytesRead=0;

    while (count) {
        PRUint32 amount = PR_MIN(count, sizeof(buf));

        rv = stream->Read(buf, amount, &bytesRead);
        if (NS_FAILED(rv)) {
            printf(">>> stream->Read failed with rv=%x\n", rv);
            //return rv;
        }

        fwrite(buf, 1, bytesRead, stdout);

        count -= bytesRead;
    }
 
    return NS_OK;
}

Hmm, en fait, j'ai utilisé un channel simple parce que je ne voyais pas comment utiliser le http channel.
