I am trying to deploy a cfg file to 5000 devices. In there I have already configured it to set the automatic proxy configuration URL. When this is done it greys out the No Proxy for Box I need to understand a) is it possible to still get Firefox to bypass proxy if you use a automatic proxy configuration URL as im not sure it does. I want Firefox to get to a number of locally hosted sites without have to first check a pac file to speed it up b) How to set the details I want to add to the No Proxy for: using about:config
