I tried it as an nsCOMPtr too. Didn't make a difference. But thank you for the
note I will change it. It is also there as a comment because i didn't know
which one is better to use.

MyListener implements QueryInterface to nsIStreamListener and
nsIRequestObserver too.
Here is the code:
/* Header file */
class MyListener: public nsIStreamListener
{
public:
MyListener(void);
NS_DECL_ISUPPORTS
NS_DECL_NSISTREAMLISTENER
NS_DECL_NSIREQUESTOBSERVER
nsCOMPtr<nsIStreamListener> mListener;
private:
~MyListener(void);
};
/* Implementation file */
NS_IMPL_ISUPPORTS2(Crypt_o_niteListener, nsIRequestObserver, nsIStreamListener)
MyListener::MyListener()
{
...
}
MyListener::~MyListener()
{
...
}
NS_IMETHODIMP MyListener::OnStartRequest(nsIRequest *aRequest, nsISupports
*aContext)
{
...
}
NS_IMETHODIMP MyListener::OnDataAvailable(nsIRequest *aRequest, nsISupports
*aContext, nsIInputStream *aInputStream, PRUint32 aOffset, PRUint32 aCount)
{
...
}
NS_IMETHODIMP MyListener::OnStopRequest(nsIRequest *aRequest, nsISupports
*aContext, nsresult aStatusCode)
{
...
}
