Currently, there is only a single Private Browsing session available. All Private Browsing tabs and windows share the same set of cookies etc.

For web programming E2E testing it would be very beneficial to be able to have multiple Private Browsing sessions in parallel.

Proposal for a simple implementation solution:

All tabs of a Private Browsing window should share the same cookie/website data context; whereas a new Private Browsing window should create a new, blank cookie/website data context.

So, given you have two Private Browsing windows, two sets of cookies/website data would be available, and all of a Private Browsing window's tabs would share that window's context.

Hi, does the container tab extension address your use case?

Thank you.

i see cookies in private tabs are not cleared and visible across new private tabs which defeats the purpose. 

Each Private tab should have their own cookies context and jit share across different private tabs.

I also noticed that I'm not able to delete all session information (i.e. cookies et al.) in a private browsing window.

If some Mozilla team will eventually take the time to create a dedicated session information jar per private window, please also (re-)add an option to empty the jar for private windows.
