Even on clearnet, no VPN or Tor or suspicious activity, even with a fresh IP.
Vanilla Chromium and Firefox don’t get the captcha but Firefox + RFP gets it.
This is very annoying, what do to fix?
To some degree, seeing captchas more frequently is just an expected irritation that comes along with strong anti-fingerprinting protections.
As an aside, if you are going as far as enabling RFP, In my opinion you really probably should be using Tor or a VPN.
RFP–and the annoyances that come with it–seem to me like disproportionate overkill if your browsing can simply be identified and correlated via your true IP address.
