What is Silk - Privacy Pass Client?
Silk - Privacy Pass Client is a Firefox extension enhancing user privacy through the use of cryptographic tokens provided by Privacy Pass protocol.

Once a supported site requests a token, Silk prompts you to solve a challenge, rewarding you with a token that can be used for anonymous authorization, helping reduce CAPTCHA interactions and streamline browsing.

Pointless addon, it just doesn't work. I've tried it for months. Right now I'm trying to access a website from almost half an hour, the page keeps on saying "just a moment" while reloading itself againg and again. A nightmare. Fuck Cloudshare
