What NoLeaker does
A free, open-source extension for Chrome 120+ and Firefox 140+. It sends the browser through your SOCKS5 proxy and makes it look like it is in the proxy’s country. No account, no license key, no servers of its own.
IP and DNS
All browser traffic and DNS lookups go through your SOCKS5 proxy.
WebRTC
Limited to proxied UDP, so pages cannot read your real IP.
QUIC / HTTP3
Upgrades are prevented, so traffic stays on the proxy.
Time zone
Date and Intl report the time zone of the proxy’s country.
Language
navigator.language and Accept-Language follow your choice.
Geolocation
Reports a point in the exit country, not your real position.
Proxy goes down
Kill switch: requests are blocked instead of going out directly.
With V2Mac, use the proxy 127.0.0.1:10808.
