When you call driver.set_window_position(x, y) using Firefox, the window position is not set. I am pretty sure this is a geckodriver issue, and I already reported it:
I am just reporting it here to track the issue on the Selenium side and will close this once fixed.
The following test is failing in Selenium's Python/Firefox CI job because of this:
FAILED py/test/selenium/webdriver/common/api_example_tests.py::test_move_window_position[firefox] - assert 0 == 50
