## Description

A Firefox extension to bypass Anubis' protection, saving your time and battery!

Anubis analyzes your browser's User Agent header. If you are on JavaScript-enabled browser, it forces you a challenge before letting you through. On the contrary, if you are not, it simply lets you walk through undisturbed.

To exploit this behaviour, this extension uses a <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/414a391560c4ad3c9f69ef494d1d3f512873ea71aca599c79bd3bf735f521ba8/https%3A//github.com/socram8888/anubypass/blob/master/hosts.json" rel="nofollow">list of known protected websites</a> for which, instead of sending your real browser User Agent that Anubis will know is JS-capable, it sends instead a unique randomized User Agent that changes every four hours.
