Spin-off of bug 117222 comment 203 and others, this should cover the design implementation of separate session cookies for new widows/tabs.

Dan, any update on this?

See bug 117222 comment 236. Basically, what needs to happen here is: 1) A design document on wiki.mozilla.org detailing the goals of this change and how it will affect UX, a preliminary spec, and implementation concerns. 2) A discussion around said wiki page, probably on m.d.platform and among the various people at Mozilla who would be interested in this. Not trying to be stop-energy here, but this is a fairly big change in behavior, and we should understand clearly what problem we're trying to solve and what new problems it might introduce. I see arguments both ways for this feature.

Also, minor point -- the distinction between session cookies and persistent cookies is largely historical and doesn't have much meaning nowadays, with the advent of sessionstore and such. I suspect that whatever we do here should apply equally to session and persistent cookies. The design document would be the place to hash this out.

Any news on this?

PB per Window is out for a while already, apparently this is fixed...

Oh good! Does this mean there is progress on this issue? [Issue 117222] can go forward?
