The Mozilla auto_config database requires an unusable CAPTCHA for Torified requests
I’ve noticed that the Mozilla configuration database
(https://live.mozillamessaging.com/autoconfig/v1.1/) often presents a
CAPTCHA when the request originates from Tor so the
method fails. We should ask if Mozilla can be more Tor-friendly.
That CAPTCHA is not displayed in the GUI so the user cannot do anything about it.
