Mozilla Firefox Server Not Found on Windows 10

After upgrading to Windows 10 all my programs couldn’t access the internet including Firefox. The solution is to do a Windows Sockets reset.

  1. Open Command Prompt (Admin)
  2. Run: netsh winsock reset
  3. Restart PC

After the restart all the programs have internet access again. Also make sure they can connect through the Windows Firewall, some of the settings were changed after the Windows 10 upgrade.
