Silk - Privacy Pass Client: Cryptographic Token Support

Silk - Privacy Pass Client is a unique Chrome extension designed to boost user privacy. It works by providing unlinkable cryptographic tokens to websites that support the Privacy Pass protocol. It aids in improving the human signal on websites, especially those guarded by Cloudflare. Upon a token request from a website, users are required to solve a related challenge, upon which a token is obtained. This extension makes anonymous authorization seamless and more secure.

Doesn't work.

Va bastante bien bloqueando los captcha, pero a veces da error y no funciona o dice que una extensión ha bloqueado la página. Totalmente recomendable si los captchas entran en bucle infinito (como es mi caso)
