I looked up how can I run silently selenium: found the next great answer here

I am trying to let selenium run regular until some action is completed and then run it in the background.

Is it possible?

thanx in advanced Oz

No, you can not change actively running Selenium WebDriver session from normal to headless and vice versa.
In the similar manner you will not be able to re-define default downloading folder, no-sandbox, disable-dev-shm-usage etc.
All these parameters are loaded during the WebDriver object creating and can not be changed for existing, running WebDriver instance.
