Downloading file to specified location with Selenium and python

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 webdriverprofile = 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()

If the application is generated dynamically (mime-types) using Chrome browser will be a better approach since the Chrome will not open the file download pop-up.But multiple download option should be enabled if you need multiple downloads.
