Private tab instead of window

[KMFi]

Functionality to open a tab for privat browsing within a normal window. For when you just need to do something in private mode, but don't won't to open a new window.

Private window, should still be an option.

that would be awesome!
Alternatively, something like "Close tab and forget data".

Use case:
Sometimes you come across websites that won’t show their content unless you accept all cookies, trackers, etc.
Going back to manually open the link in a private window, copying/pasting the URL, using a separate container or even a different profile - all of that works, but it's rather cumbersome.

plus control of how that "private tab" would look versus other open tabs

Dear Mozilla Firefox Team,

I would like to submit a feature request to introduce more granular, domain-specific privacy and data management controls in Firefox. My proposal consists of two main features that would be highly beneficial for both regular users and developers:

1. Automated Data Deletion on Tab Close (Per-Domain)
Implement a setting that automatically clears all site-related data when closing a tab for a specific domain. Support wildcard configurations for subdomains (e.g., *.example.com). Allow users to choose exactly which data points are deleted (e.g., selectively clearing browsing history, session data, or cache).

2. In-Window Private Tabs and Domain-Specific Private Modes
Introduce a "New Private Tab" option that opens within the current browsing window, removing the need to open a completely separate Private Browsing window. Allow users to configure specific domains to automatically open in this "Private Tab" mode. Provide detailed settings for these domains regarding the handling of local data structures, such as IndexedDB.

These enhancements would be a significant step forward for customizable privacy and provide excellent debugging tools for web development.

Thank you for your time and your continued great work on Firefox.
