In Safari, while browsing using a private window, you can log in to a service then open a new tab and go to the same service and log in to a separate account. This same concept works for carts (i.e. 2 separate tabs of the same website with different carts) or anything else that stores session data.

Is there a browser for Windows that supports the same idea? Safari is no longer supported on Windows and both Chrome and Firefox share session data across all private tabs and windows.

I did find a similar question, but it was asked over 4 years ago and proposed solutions required extensions to be installed

Firefox/Waterfox support something called Multi-Account Containers which can be enabled by a config change or an official extension installation.

I personally use it together with the Temporary Containers** extension set to automatic, so unless specified, every tab is a completely separate browser session.

** If you use Waterfox, temporary containers automatic mode requires a manual hack.



It is a builtin Firefox feature, does not require add-ons.

You need to start Firefox with the --ProfileManager --no-remote command line flags.

To set it up, read this: How to add command line options to a shortcut?

  • While this is an option, I recommend you check out Multi-Account Containers for a much more convenient solution (see my answer)

Try Ghost Browser that fulfills your tab isolation requirement. Because Ghost Browser is specially designed for multi-login purposes. Each time you open a new tab, you can put it into a new Session. Newly tab has separate tab colors so you can easily distinguish among them.
