After setting these preferences the browser won't show up pop dialog asking for whether you want to download save or other.
When can then just use find_some_eleme = driver.find_element_by_xpath('''''').click() we can use any other method of locating the element xpath/id/css/name... and we use the method click() freely because there won't be a dialog.
or .setPreference("browser.helperApps.neverAsk.saveToDisk","application/octet-stream,text/csv")
For Chrome:
chromedriver = "path/to/chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
chrome_options = Options()
# this is the preference we're passing
prefs = {'profile.default_content_setting_values.automatic_downloads': 1}
chrome_options.add_experimental_option("prefs", prefs)
driver = webdriver.Chrome(chrome_options=chrome_options)
