Downloading file to specified location with Selenium and python

by

You need to make Firefox save this particular file type automatically.

This can be achieved by setting browser.helperApps.neverAsk.saveToDisk preference:

from selenium import webdriver

profile = webdriver.FirefoxProfile()
profile.set_preference("browser.download.folderList", 2)
profile.set_preference("browser.download.manager.showWhenStarting", False)
profile.set_preference("browser.download.dir", 'PATH TO DESKTOP')
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/x-gzip")

driver = webdriver.Firefox(firefox_profile=profile)
driver.get("Name of web site I'm grabbing from")
driver.find_element_by_xpath("//a[contains(text(), 'DEV.tgz')]").click()

More explanation:

  • browser.download.folderList tells it not to use default Downloads directory
  • browser.download.manager.showWhenStarting turns of showing download progress
  • browser.download.dir sets the directory for downloads
  • browser.helperApps.neverAsk.saveToDisk tells Firefox to automatically download the files of the selected mime-types

You can view all these preferences at about:config in the browser. There is also a very detailed documentation page available here: About:config entries.

Besides, instead of using xpath approach, I would use find_element_by_partial_link_text():

driver.find_element_by_partial_link_text("DEV.tgz").click()
