Python, Selenium, download all MIME types

Question

I am trying to download some files using selenium webdriver for Firefox. How to set option browser.helperApps.neverAsk for any MIME type?

Now this option working only for application/pdf (in my script):

#selenium profile
profile = webdriver.FirefoxProfile()
profile.set_preference('browser.download.dir', download_dir)
profile.set_preference('browser.download.folderList', 2)
profile.set_preference('browser.download.manager.showWhenStarting', False)
profile.set_preference('browser.helperApps.neverAsk.saveToDisk', 'application/pdf')
#-------------------
driver = webdriver.Firefox(firefox_profile=profile)

Answer 1

You have to list the mimetypes explicitly and separate the values with commas:

profile.set_preference('browser.helperApps.neverAsk.saveToDisk',
                       'application/pdf,text/csv')
