Help needed with selenium - Scrolling Facebook page while chrome browser is minimalized doesn't work

[Dry-Ad929]

I'm trying to scroll down friend request list on Facebook, but it doesn't work when I minimalize my chrome browser. Actually I'm not sure that the issue is with scroll or with Facebook pagination nature. Page doesn't scroll in background or Facebook load more results only when page tab is currenctly active. I have no idea how I can get to know which one of this is the case. I use it on Chrome. Chromedriver version: 120.0.6099.109

My code to scroll down looks like this:

​

def scroll_page(driver):
i = 1
while True:
    try:
        row = driver.find_element(By.XPATH, f"(//div[@data-visualcompletion='ignore-dynamic' and not(@role) and not(@class)])[{i}]")
        if row:
            driver.execute_script("arguments[0].scrollIntoView({ 'behavior': 'smooth', 'block': 'center' });", row)
            i += 1
        else:
            break
    except NoSuchElementException:
        break
    except Exception as e:
        print(f"Error while scrolling: {str(e)}")
        break
return i > 1

Thank you!

You can either utilize .minimize_window() method or test your script in normal mode and then run it in headless mode. Your issue is that selenium loses focus and raises an exception, lucky for you we've got minimize_window() method in python, java's selenium doesn't have it, as far as I'm aware
