I have problem with Selenium WebDriver and Firefox. I want to download csv file without confirmation in dialog window and I have code like this:

fp = webdriver.FirefoxProfile()
fp.set_preference("browser.download.folderList",2)
fp.set_preference("browser.download.dir", download_dir)
fp.set_preference("browser.download.manager.showWhenStarting",False)
fp.set_preference("browser.helperApps.neverAsk.saveToDisk","text/csv")

but it seems not working. I tried many combination with browser.helperApps.neverAsk.saveToDisk 

fp.set_preference("browser.helperApps.neverAsk.saveToDisk","text/csv,application/csv,text/plan,text/comma-separated-values")

or

fp.set_preference("browser.helperApps.neverAsk.saveToDisk","application/csv")
fp.set_preference("browser.helperApps.neverAsk.saveToDisk","text/plain")
fp.set_preference("browser.helperApps.neverAsk.saveToDisk","text/comma-separated-values")

but there's no difference and Firefox won't download automaticly. How can I fix it?

Sometime the content type is not as you'd expect Use HttpFox Firefox plugin (or similar) to find the real content type of the file and use it in your code

BTW, For me the content type was 

fp.set_preference("browser.helperApps.neverAsk.openFile", "application/octet-stream");
fp.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/octet-stream");

Now (May 2016), 

 SetPreference("browser.helperApps.neverAsk.saveToDisk", "text/csv"); // C#

works for me
