How to run two copies of the browser?

Question

Browsers

Can't login with the same username and password. Open copies of the browser does not work.
Tried Firefox Portable. Made in FirefoxPortable.ini? but alas, it does not allow launching the second copy of the portable FireFox. Portable and normal please, but it doesn't suit me, I need at least 4 copies. Google Chrome suggests launching a browser with parameters that will open each copy as a different user, but this does not suit me. AllowMultipleInstances=true

Answer 1

We start with the parameters firefox -p -no-remote
tyks or tu-ta

Answer 2

Umm.. if you just need to go to the same site with different logins/passwords at least 10 times, just install the wonderful Temporary Containers extension . You can open clean, completely independent tabs in a single browser window. Each tab will have its own cache, cookies and other data. So you can use different logins on the same site.
If the site checks account activity and allows only one session, then two copies of the browser will not solve the problem

Answer 3

well, you can use Sandbox to launch multiple copies... but the system will assume that these are different browsers most likely ..

Answer 4

Try to open a second session in incognito mode

Answer 5

As an option:
1. Create a virtual machine.
2. Launch the browser, log in to the site you need.
3. Send the virtual machine to hibernation.
4. Clone the hibernated virtual machine.
At the same time, the cloned virtual machine will have the same system with the same cookies when exiting hibernation. Well, instead of hibernation, perhaps you can use a snapshot.
