Allow for multiple parallel Private Browsing sessions.

[WhiteKnight]

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.

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

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

[WhiteKnight]

Thank you.

@rtestard: I'm working on different client machines at my customers'. Installing extensions may widely be blocked.

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.

This would also be very helpful in the MSP space. We log into many clients' tenants throughout the day and often need to be in multiple simultaneously. Currently, I use different browsers and/or Firefox profiles for this, but the ability to do it in one instance of Firefox instead of running multiple would be beneficial.
