I don't think so. Try https://ipv6-test.com/ and http://test-ipv6.com/ they will tell you what protocol your browser prefers and if it tends to fall back to IPv4. There you can also compare your speed over IPv4 vs IPv6.

The tweak for Firefox is or was user_pref("network.http.fast-fallback-to-IPv4", false);
