Install the PrivacyPass Firefox or Chrome extension. It was developed by Cloudflare, Firefox, and Tor in partnership. It has you answer a ReCAPTCHA and using some crypto magic, generate a bunch of CAPTCHA bypass tokens that can't be traced to your specific computer.
The plugin requires "privacy passes". Those passes can be obtained by solving captchas, but when trying to do so, one is greeted with this message about being blocked: https://i.imgur.com/qXJfl6J.png
This sort of breaks tor though, doesn't it? Tor works really well if you stay on the same circuit for a while since it reduces the chances you have a compromised circuit. If you start getting recaptcha to block every exit node except those you control, you essentially have amplified your effective strength on the tor network.
This sounds pretty good, but you still have to pass a captcha in order to get a pass, and sometimes that is impossible (or at least I just give up because I lost interest after 20 puzzles).
If it was developed in conjunction with Tor, how come it doesn't come bundled with the Tor browser or Tails?
