when I go to bookmarks or click on web address this message always pop up. I can't get this to stop even when I dis able the yahoo from being active. So how do I get this fixed or repaired? Server not found Firefox can't find the server at signin.ebay.com. Check the address for typing errors such as ww.example.com instead of www.example.com 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.
