Add dFPI to the preferences page, so users can easily set this as their choice. This will be an option in custom in the cookies dropdown.

Erica, could we get that added to our nightly-only release notes please? Thanks

Release Note Request (optional, but appreciated)
[Why is this notable]: in Nightly only users may turn on first-party isolation in their settings by changing their Enhanced Tracking Protection mode to Custom, and selecting "cross site and social media and isolate remaining cookies" when choosing which cookies to block.
[Affects Firefox for Android]: No
[Suggested wording]: We're experimenting with a more web-compatible version of first-party isolation, which double keys all third-party state by the origin of the top-level context.
[Links (documentation, blog post, etc)]: Please contact Steven Englehardt for more information if needed.

Is this dFPI pref interfering with privacy.firstparty.isolate about:config?

It shouldn’t have any effect if you already have first party isolation turned on. With that said, we’re still looking into possible edge cases. If you like feel free to enable the new preference and please file bugs if you notice anything odd/different with both turned on.

Nightly only, not going to be in relnotes until it ships, so clearing the flag.
