Accessing websites using Tor Browser (in both Desktop or Android version) works, but when using Privacy Browser + Orbot VPN the CloudFlare system block the access.

Is there anything that can be done to avoid Privacy Browser having a different fingerprint and not be blocked?

An example:

  • Priority changed from 3.x to 4.x

Cloudflare is subjecting all traffic from known Tor exit nodes to a CAPTCHA. You can verify this by using Orbot in VPN mode and trying a number of browsers (Chrome, Firefox, Lightning, FOSS Browser).

However, a year ago Cloudflare created a mechanism for the Tor Browser to automatically redirect normal URLs to .onion URLs that don't product the CAPTCHA. You can read about it here:

There isn't anything I can do about it in Privacy Browser with the current WebView, but it would be possible to enable similar functionality in Privacy WebView in the 4.x series.
