Status: RESOLVED FIXED

(Core :: Privacy: Anti-Tracking, defect)

Description

[Simona Badau, Desktop QA]

Attachment: Screen recording with the issue

Found in

• Firefox 118

Affected versions

• Firefox 118.0b4
• Nightly 119.0a1

Tested platforms

• Affected platforms: macOS 11.7, Ubuntu 20.04 and Windows 10

Steps to reproduce

1. In a normal window - open about:preferences#privacy
2. Open a new private window and open about:prefecences#privacy
3. In the normal window, either uncheck the "Suspected fingerprinters" option or change the dropdown to "In all windows".

Expected result

• The modification made in step 3 in the normal window should immediately reflect in the private window on the about:preferences#privacy page.

Actual result

• The change made to the "Suspected fingerprinters" setting in the first window does not appear in the second window unless the page is refreshed (F5 is pressed).

Regression range
Not a regression, it was implemented like this in Bug 1841097.

Additional notes
If a similar change is made to the "Tracking content" setting, the change is immediately visible on both about:preferences#privacy pages.

:sbadau, if you think that's a regression, could you try to find a regression range using for example mozregression?
