What is the current behavior?

When trying to launch Firefox with a Private mode flag, it opens two windows: one regular and one private. And tests run in the regular window.

What is the expected behavior?

One window should be opened and, more important, test should run in the Private window.

How would you reproduce the current behavior (if this is a bug)?

testcafe "firefox -private-window" tests/test.js

Provide the test code and the tested page URL (if applicable)

Hello @Vitalii4as,

Could you please clarify why it's necessary for you to run the test in Private mode?
