Simple problem but i dont know the solution

Hello Guys!
I have some small problem.
So the task is i need to open many firefox private windows. Windows, not a tabs. When i amd doing it in a normal way ( using open browser activity) w/o private selected its opening as its supposed to open( as new instances) BUT when i try to do same with private activated its just opens for me one firefox instance and new private tabs in that. But i need all to be opened as new instances of firefox. And after i need to attach each of the broser to the some variable
Somebody suggest a fix? Thank you in advance

Hi maksustuyanov

Did you try the communication method property of the Open browser
When it is selected to webdriver it opens the browser in multiple windows even if Private is true.
Please try it out and let me know if it works for you.
