Streaming problem

I stream various radio stations while I surf around using Firefox. Since an upgrade to 20.0.1 I notice that the stations drop out every now and then for a few seconds, sometimes I have to refresh the tab that the station is on. The problem I have now is that I have been using this interactive flash based tutorial and every time I click any button, the streaming radio stops and I have to refresh the page. Is there a setting that may change this or is it a bug that needs to be fixed? If so, where do I report a bug?
Many thanks.
