Description

[David Olah]

Attachment: simplescreenrecorder2-2019-02-14_15.57.22.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 privacy page and check only Fingerprinters
2. In a new tab, go to: https://www.bizjournals.com/
3. Check the Shield icon menu and see that a Fingerprinter is blocked.
4. Go back to privacy and check Trackers -> In all windows (also let Fingerprinters checked)
5. In a new tab, go to: https://www.bizjournals.com/
6. Check Shield icon menu

[Expected result]
Trackers are blocked and also the Fingerprinter shown at step 3.

[Actual result]
Trackers are blocked and Fingerprinters doesn't appear - no Fingerprinter is blocked.

[Note]
I tought that the Fingerprinter is included in a Tracker, and it is not found because activating the Trackers blocks the Fingerprinter automatically, but I cannot find any tracker with the same name as the Fingerprinter.

This works as expected, the fingerprinter is loaded by https://assets.adobedtm.com/4ea7bf50a24b9cc15d03d9f7a75a849dfbcc6242/scripts/satellite-580e6c3964746d5fda009a19.js (which is a tracker).
