The usage of this add-on is simple. Users just need to open the plugin, wait for the QR code to be refreshed, and then select a QR code. After that, they can open the Shadowsocks client and choose to scan the QR code. Once the scan is successful, they can check the Shadowsocks client and start accessing websites that are blocked.
