Neither the userscript nor the browser extensions work at all

### What happened? I tried all methods described in the README but I just cannot view videos that have been age restricted without being forced to log in. I tried using the userscript in Tampermonkey, I also tried both browsers, manually installing the Firefox extension and the Chrome extension. It just doesn't work. YouTube still forces me to sign in, no matter what I do. Nothing works and thus this is completely useless. ### Platform Other (mention above) ### Version Latest from this GitHub repository ### What browser are you on?
