The computer "239.255.255.250" is attempting to access Firefox.app on your computer. Do you want to allow this connection?

What is this for? And if it is innocuous, can I just say allow? Just started in last 2 weeks (end of Feb 2015). It is bugging the heck out of me. Thanks.

hello kvoliver23, this is caused by the "Send Video To Device" feature that landed in firefox 36 - if you don't use that you can safely block these requests. More information is available at How to stop Firefox from making automatic connections (under "Media capabilities" in particular).
