1312655 - checkbox in about:preferences#privacy for privacy.firstparty.isolate (Tor 20244.2)

Status: RESOLVED WONTFIX

(Firefox :: Settings UI, defect, P3)

Description

[Arthur Edelstein [:arthur]]

In Tor Browser, we introduced a patch that adds a checkbox in about:preferences#privacy that controls the "prviacy.firstparty.isolate"* preference. (This pref is default-off in Firefox, but default-on in Tor Browser.) We would like to proposing uplifting this patch at some point, if possible.

Here is current the Tor Browser patch:

This bug's summary should include "privacy.firstparty.isolate" instead of "privacy.resistFingerprinting", correct?

Oops. Thanks!

As discussed in the project meeting, it is not necessary to resolve this bug before ESR 52.
Tor Browser can uplift this patch on their side.
So flag it as P3.

Also as discussed, Tanvi suggested that we can add a new section in about:preferences#privacy which is hidden in release and only appears in Firefox Nightly.

Tanvi, do you know who can help on this? jkt maybe?

Yes, jkt or maybe Francois.  Also someone on the fxprivacy team (Johann, Nihanth, Paolo, Florian).

But it seems like it would be pretty straight forward, so perhaps someone from your team can try it out and consult one of the above people for mentorship if they get stuck.

Instead of adding a hidden preference, we plan to add the checkbox for FPI only in Private Browsing mode.
Also refer to bug 1397624 for the pref work.
