Python Set Firefox Preferences for Selenium--Download Location

Question

I use Selenium Marrionette and GeckoDriver to pull web data. I use the following to set my Firefox profile preferences:

fp = webdriver.FirefoxProfile()
fp.set_preference("browser.download.folderList", 1)
fp.set_preference("browser.helperApps.alwaysAsk.force", False)
fp.set_preference("browser.download.manager.showWhenStarting",False)
fp.set_preference("browser.download.dir", "H:\Downloads")
fp.set_preference("browser.download.downloadDir","H:\Downloads")
fp.set_preference("browser.download.defaultFolder","H:\Downloads")

binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\Firefox.exe')

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True

driver = webdriver.Firefox(capabilities=firefox_capabilities, firefox_binary=binary, firefox_profile = fp)

From what I understand after reading Unable to set firefox profile preferences and FirefoxProfile passed to FirefoxDriver, it seems that nothing is being done when using firefox_profile now. So I need to implement the new updates to firefox_capabilities, but I'm not sure how to exactly do that. Any ideas?

Ok, I believe I finally figured this mess out. Instead of using the code above, I used the following code which I point to my Firefox profile folder(if you need to update your default profile settings do that in Firefox before running this code):

from selenium.webdriver.firefox.options import Options
binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\Firefox.exe')
fp = (r'C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\oqmqnsih.default')
opts = Options()
opts.profile = fp
firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True
driver = webdriver.Firefox(capabilities=firefox_capabilities,firefox_binary=binary, firefox_options = opts)

I ran this code along with my web-scraping code and once I clicked the "Export CSV" link, it automatically downloaded as opposed to the Download Manager window popping up. Feel free to add any feedback.

the solution for my python script (on raspi 3):

binary = FirefoxBinary('/usr/bin/firefox')
driver = webdriver.Firefox(capabilities={'browserName': 'firefox' }, firefox_binary=binary)

The initial code is partialy correct. You must set browser.download.folderList value as 2 :

fp = webdriver.FirefoxProfile()
fp.set_preference("browser.download.folderList", 2) # 0 means to download to the desktop, 1 means to download to the default "Downloads" directory, 2 means to use the directory 
fp.set_preference("browser.helperApps.alwaysAsk.force", False)
fp.set_preference("browser.download.manager.showWhenStarting",False)
fp.set_preference("browser.download.dir", "H:\Downloads") 

binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\Firefox.exe')

firefox_capabilities = DesiredCapabilities.FIREFOX
firefox_capabilities['marionette'] = True

driver = webdriver.Firefox(capabilities=firefox_capabilities,firefox_binary=binary, firefox_profile = fp)
