When I try to open an ad, I get the message "Unable to connect Firefox can’t establish a connection to the server at www.googleadservices.com. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web." My firewall etc. allow me to access Firefox for everything else, so I don't think they are causing this error message. Is there a place in Firefox setup to prevent ads from showing? If so, I can't find it.
