Ok, thank you. So it really might be a problem for me. Fortunately the FF will be one
of the least important browsers for my project. I decided, that this really is a FF
bug, and regardless what the FF devs might say not a feature. I understand it, when a
browser fetches pages, which I only might want to get. But I send mine a single html 
page with no further links, so it really downloads everything there is. Opening a socket
to this page's address and port whenever the page sends data to a totally different 
websocket connection does not make not the least bit of sense.
