リスク: QUIC (HTTP/3) fallback exposing direct local ISP connection
修正: Launch browser profiles with --disable-quic flag or enable UDP forwarding.
リスク: Local ISP or network firewall blocking proxy ports (Rare Edge Case)
修正: VLESS is ONLY needed if your ISP or country actively blocks standard SOCKS5 ports (e.g. strict firewall rules). Otherwise, SOCKS5 is completely sufficient.
Use SOCKS5 + WebRTC = Altered/Replace and --disable-quic. No complex VLESS setup required.
