That was interesting, thank you. I first set `general.useragent.override` to empty and as you say arstechnica.com 403ed. I then set it to `Hello, I am a human`

That was interesting, thank you. I first set `general.useragent.override` to empty and as you say arstechnica.com 403ed. I then set it to `Hello, I am a human` and arstechnica.com worked just fine. Oddly google.com renders a basic mobile-like UI.
