Status: RESOLVED WONTFIX

(Firefox :: Protections UI, defect)

Description

[David Olah]

Attachment: bandicam 2019-02-15 15-32-37-845.mp4

[Affected versions]
latest Nightly 67.0a1

[Affected platforms]
Windows 10 x64
macOS 10.13
Ubuntu 16.04 x64

[Prerequisites]
Launch Firefox on a clean profile.
Set the following prefs to true in about:config

privacy.trackingprotection.cryptomining.enabled
privacy.trackingprotection.fingerprinting.enabled
browser.contentblocking.cryptomining.preferences.ui.enabled
browser.contentblocking.fingerprinting.preferences.ui.enabled

[Steps to reproduce]

1. Go to Content blocking Preferences page and check all 4 options (Tracking, Cookies, Fingerprinting, Cryptomining)
2. In a new tab, go to a page that contains Trackers, Cookies and Fingeprintes or Cryptominers(Ex: https://www.bizjournals.com/)
3. Check that Trackers are shown, Cookies are shown and Fongerprinters or Cryptominers are shown and blocked (in the Shiel icon menu).
4. Go back to Content blocking privacy page and uncheck all the options.
5. In a new tab, go to the same page as at step 2 and check the Shield icon menu

[Expected result]
All the found items are shown (Trackers, Cookies, Fingerprinters/Cryptominers) but not blocked.

[Actual result]
Trackers and Cookies are shown even if they are not blocked, because they are found. The Fingerprinters/Cryptominers sections disappear once they are unchecked in the preferences page.

[Note]
Regarding the fact that Trackers and Cookies are shown if being found even when the checkboxes are unchecked, creates a inconsistency between Trackers and Cookies vs. Fingerprinters and Cryptominers.

Yes it's inconsistent but this is currently intentional to not draw too much attention to this WIP experimental feature.
