I do not know what to do about this: Firefox and Internet Explorer will not let me load/find/visit craigslist. Comodo Dragon will allow it without any trouble.
The browser window message shows this:
Server Not Found.
If your computer or network is protected by a firewall or proxy, make sure
that Firefox is permitted to access the Web.
System is: Wireless internet connection through AT&T, Windows XP s.p.3, Norton Internet Security v20.2.0.19, Internet Explorer 8, Firefox 17.01... Same exact system for at least two months (except for the update of Firefox). Everything else the same for much longer than two months (except for NIS update from version 5 to version 20 about two months ago).
What can I do? Right now only craigslist seems to not be happening on Ffx and IE but its good on Cmodo Dragon browser. How do I investigate? How do I adjust? Firewall? I wouldn't know.
