Affected versions

  • Firefox Nightly 71.0a1 (2019-10-20)

Affected platforms

  • macOS 10.14
  • Windows 10 x64
  • Ubuntu 18.04 x64

Steps to reproduce

  1. Launch Firefox.
  2. Go to about:preferences#privacy and from Custom section un-check all items expect for "Fingerprinters".
  3. Go to
  4. Observe "Help the Community" section.

Expected result

  • "Help the Community" section should be displayed.

Actual result

I'm not able to reproduce this. I don't see any fingerprinters blocked on this page, and I am able to see the "Help the Community" box with fingerprinting blocking enabled. Hani, would you mind to confirm that you see a fingerprinting domain in the content blocking doorhanger and share the fingerprinting domain?

I suspect Yelp is A/B testing this box. I initially didn't see it on any pageload (even with content blocking off). I then cleared my browsing history and started seeing it on every pageload (with fingerprinting blocking enabled).

Closing this bug as resolved invalid.
I don't see any Fingerprinters blocked on this page either now, but somehow only when Fingerprinters were enabled I managed to reproduce the issue mentioned above.
