How to set window position of Firefox browser through Selenium using FirefoxProfile or FirefoxOptions

问题

I need to change the position of the Firefox window by creating the driver with:

driver = webdriver.Firefox()

I know it's possible to change the window position after the driver was created:

driver.set_window_position()

I can't find out how to do it using Firefox profile or options:

profile = webdriver.FirefoxProfile()
profile.set_preference("some_preference", my_preference)

or

options = Options()
options.some_optins = my_options

and finally:

driver = Webdriver.Firefox(firefox_profile=profile, options=options)

You saw it right.

set_window_position()

set_window_position() sets the x,y position of the current window.

• Implementation:

  set_window_position(x, y, windowHandle='current')
  Sets the x,y position of the current window. (window.moveTo)
  
  Args :  
      x: the x-coordinate in pixels to set the window position
      y: the y-coordinate in pixels to set the window position
  Usage : 
      driver.set_window_position(0,0)
  

• Defination:

  def set_window_position(self, x, y, windowHandle='current'):
      if self.w3c:
          if windowHandle != 'current':
          warnings.warn("Only 'current' window is supported for W3C compatibile browsers.")
          return self.set_window_rect(x=int(x), y=int(y))
      else:
          self.execute(Command.SET_WINDOW_POSITION,
               {
                   'x': int(x),
                   'y': int(y),
                   'windowHandle': windowHandle
               })
  

So to summarize, window_position is coupled to the window handle pertaining to the browser and can be handled by webdriver instance only.

This functionality can't be handled either through :

• firefox_profile -> set_preference(key, value): Sets the preference that we want in the profile.
• firefox.options -> set_preference(name, value): Sets a preference.
