Open MPEG streams in a external player from firefox

Hello,
I have got a DVB server that streams TV channels at home. In Firefox ESR you just click in the stream and it's loaded in the embedded VLC player. Pretty convenient.
But how do I do this in newer firefox versions? I can configure it to use VLC (or other player) as default but it tries to downlad the file and then open it with VLC, since this is a stream the file has no end and it keeps downlading it.
Any idea?
