earthlink is my ISP and I use firefox to connect to my earthlink home page. I get this message "server not found firefox can't find server at ad.doubleclick.net but everything works can surf etc. Earthlink says it is not their problem is earthlink not compatible with firefox or are the techs at earthlink not knowledegable for this problem. They say it is a firefox problem,but this has occurred recently everything worked well a few weeks ago
