I'm currently using the latest firefox (57.0). While having multiple windows / instances of firefox running, my router will restart. There is no error messages prior to the router shutting off. Takes about 1 minute for internet to come back on. The router crash seems to happen while playing youtube / twitch.tv on each firefox instance. It's almost as if firefox is demanding too much bandwidth and it's shutting the router off. I dont have this issue with other browsers. Router: NetGear DGN2200v3 Firmware Version V1.1.00.25_1.00.25NA
