I can't connect to MSN, AIM,nor can I open the launchers for some MMOs I play (though I can get into them if I launch the .exe file). I can connect to Steam and talk to people but I can't use the browser aspect of it. Firefox says it's a proxy issue, but I'm not too software savvy and don't really know what to do with this. It seems to be anything browser-related. I haven't installed anything new and I ran a few scans for viruses, malware, etc, and did a few other things I usually do to remedy connection issues (disabling firewall, power cycling modem/router, etc) to no avail. Does anyone know how to fix this?
