1130655 - Private browsing windows should use separate contexts

Status: RESOLVED DUPLICATE of bug 117222

(Firefox :: Private Browsing, enhancement)

Description

[Ralph Giles (:rillian)]

I'd been hoping different private browsing windows were isolated from each other, but per bug 1053875 it seems this is not the case.

Can we add support for multiple private browsing profiles which do not interact? I'd suggest for example that they be per-window or per-domain, to avoid confusion with dropping login credentials on secondary tabs.

Use case:

Private window one contains the NSA probe interface I'm using to adjust surveillance on my coworkers. Private window two contains the secret EFF cabal forum. Without separation I can't have both of these open at once without 'like' buttons confirming to Facebook that I'm a double agent.

This should be possible without running separate browsers for each, which would tip off my coworkers.

To verify:

1. Open new private browsing window.
2. visit https://mozillians.org/
3. open the devtools console
4. enter document.cookie = 'hello from private browsing!';
5. Open another new private browsing window.
6. visit https://mozillians.org/
7. open devtools console
8. enter document.cookie
9. observe string from step 4 copied to the new window.

Thanks to Jeff for the example.
