every time I open comcast or any page, I get a pop up that says 'opening rpc.html. The text says I have chosen to open rpc.html which is a: Firefox Document from:http://xfinitytx.comcast.net Then it asks 'What should Firefox do with this file? I don't subscribe to xfinity although I use Comcast as my provider. How do I stop this pop up?
