6to4 Tunnel

"We have detected you are using a 6to4 tunnel. 6to4 is deprecated and will be shutdown shortly."

I keep getting this message. The past few times it would simply ask me to verify I am not a robot (from google search). Today it simply says this.

Any ideas on how I fix this?

Thanks

Using Google search, I presume? I think this problem is caused by older router firmware that doesn't support IPv6 addresses.

If your router has an update available, that would be the best approach: https://www.reddit.com/r/firefox/comments/hmc3t0/google_search_forcing_captcha_dialog_6to4_tunnel/

If not, you could try disabling Firefox from using IPv6 addresses:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste ipv and pause while the list is filtered

Experiment #1:

(3) Double-click the network.dns.ipv4OnlyDomains preference to display an editing field, and enter

www.google.com

(or your actual Google search site if you use a different one) then press Enter or click the blue check mark button to save the change.

You may need to clear cache to make sure Firefox requests a new address:

How to clear the Firefox cache (this should be limited to cache and not include cookies/history)

Experiment #2 (if #1 doesn't work):

(4) Double-click the network.dns.disableIPv6 preference to switch the value from false to true

(You may need to clear cache to make sure Firefox requests a new address)

Does that work? Please let us know because this question is coming up more often in recent days. Thanks.
