First Party Isolation is an absolutely necessary privacy feature. Firefox is supposed to provide privacy by default, and be opinionated.

Please enable FPI by default.

I have heard concerns about FPI breaking things, but really the only things which break are those abusing the lack of FPI.

Info about FPI for those who don't know: ... n-firefox/

this forum is free and voluntary maintaining firefox. no mozilla developers present, sorry.
go instead.
The following items are affected by First-Party Isolation: cookies, cache, HTTP Authentication, DOM Storage, Flash cookies, SSL and TLS session resumption, Shared Workers, blob URIs, SPDY and HTTP/2, automated cross-origin redirects,, auto-form fill, HSTS and HPKP supercookies, broadcast channels, OCSP, favicons, mediasource URIs and Mediastream, speculative and prefetched connections.

ok, in other words: an aluhelmet. i dont see benefit limiting firefox in its features and have wrong shown pages. welcome to the real world of 3rd-party cookies.

It appears you think the independent is a part of or run by Mozilla as there is no links on top or bottom like a typical * page as one of the clues.

Mozilla has their own community support forum at btw.
