Prerequisites

  • Go to about:config and set the preference "privacy.purge_trackers.enabled" to true.
  • Make sure that in the Settings of the Web Console, "Enabled browser chrome and add-on debugging toolboxes" is checked.

Steps to reproduce

  1. Launch Firefox
  2. Navigate to https://edition.cnn.com/
  3. Scroll down to the Paid section and open the IBM articles:

  1. Close all the tabs from the previous steps
  2. Go to about:preferences#privacy and observe all the cookies from the "Manage Cookies and Site Data" dialog.
  3. Open the Browser Console, type and enter `Services.obs.notifyObservers(null, "idle-daily");' to send the idle-daily notification manually.
  4. Check again the cookies from the "Manage Cookies and Site Data" dialog.

Expected result
In step 6, only the cookies from the Disconnect Tracking Protections list should be cleared.

Actual result

  • In step 5, multiple IBM cookies are generated, but not all of them are on the Disconnect Tracking Protection list.
    www.ibm.com
    idaas.iam.ibm.com
    ibm.com
    cloud.ibm.com
    www-api.ibm.com
    myibm.ibm.com
    api.marketplace.ibm.com

  • In step 6, all the cookies that contain "ibm" are deleted, even if only "www.ibm.com/" and "ibm.com" are on the Disconnect Tracking Protections list.

All of these are trackers as classified by about:url-classifier.
