Is it possible to capture HTTP/3 traffic from chrome?

[MouadA]

Since ALL browsers ignore socks5 proxies on UDP traffic, is there another way to capture it
I specifically want HTTP/3 because FunCaptcha flags whoever is on a modern browser and the request is forced to HTTP/2

You're right—most browsers don’t support SOCKS5 for UDP traffic, which limits direct handling of HTTP/3. To capture it effectively, you might consider using a system-level proxy like a VPN or tun interface that routes all traffic, including UDP. Tools like Wireshark or mitmproxy (with QUIC support) can also help analyze HTTP/3 if configured correctly.

To protect yourself from UDP requests, you need to use a VPN. But FunCaptcha uses fingerprints, it knows how your graphics are drawn. You need to patch Chrome or disable Canvas, WebRTC, Webgl

You can install something like Mitmproxy with a custom certificate in chrome.

You can disable QUIC completely in Chrome/Chromium and force it to HTTP/2.

Disabling HTTP/2 can be detected by the captcha
