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

>Solution :
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.
