How to create a cookie for different tabs of the same site?

Question

proxy

Greetings, brethren.
Is it possible to open the same site in several tabs, only with different cookies?
To explain in more detail: there are many accounts that must have an active session with individual cookies. You can run many portable versions of browsers in order to implement this. But every running browser eats a lot of RAM.
So the idea came up, maybe he will use it less if he is essentially one, but each tab (with the same site) has different cookies. Maybe this way it will cache information more.
It would be ideal if, like the hosts file, the browser would treat each open site as another (for example, name1.site, name2.site) and create a new session for each, but refer to the same site ip.
Is it possible to implement something like this?

Answer 1

swSpyBrowser is the most suitable option, it is used just for all sorts of incomprehensible things like cheats, etc.
also in normal browsers it is possible to create users, each has its own isolated space. But it is not so convenient naturally.

Just don't forget that your browser fingerprint will burn you
