You will have to use FirefoxProfile for this action (indentation may be broken):

fprofile = webdriver.FirefoxProfile()
fprofile.set_preference("browser.download.dir", "/Desktop/test-download")
fprofile.set_preference("browser.download.folderList", 2)
fprofile.set_preference("browser.download.manager.showWhenStarting", False)
fprofile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/vnd.ms- 
powerpoint")
driver = webdriver.Firefox(firefox_profile=profile)
