Currently, all private windows share the same context, including cookies and cache. It would be a great if we could create multiple isolated private windows, offering several advantages:
With isolated private windows, logins made in one window would remain separate and not visible in others, providing isolation. This prevents other websites from detecting the session or users from accidentally granting access to a different site while using the same credentials.
It can effectively limit cross-site tracking by preventing trackers from connecting user data across different private windows. This would make it significantly more challenging for advertisers and data collectors to compile comprehensive user profiles.
Developers would benefit from the ability to create multiple isolation spaces within private windows for testing and debugging purposes.
