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.

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)
