At this point you may right-click the Shadowsocks tray icon and Enable System Proxy. Then right-click the icon again and enable Mode -> Global. This will update system-wide proxy settings – this will work for Google Chrome as well as Microsoft Internet Explorer.
Alternatively, manual browser configuration is possible:
Proxy type: SOCKS v5
Proxy IP (Socks Host): 127.0.0.1
Port: 1080
