I'm trying to automatically download .pdf files in geckodriver/Firefox. I've searched on stackoverflow and other resources and think the code below should work: 

profile.set_preference("browser.download.folderList", 2)
profile.set_preference("browser.download.manager.showWhenStarting", False)
profile.set_preference("browser.download.dir", 'C:\\Users\\xyz\\Downloads\\')
profile.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/octet-stream,application/pdf,application/x-pdf,application/vnd.pdf")
profile.set_preference("pref.downloads.disable_button.edit_actions", True)
profile.set_preference("browser.helperApps.neverAsk.openFile", "application/octet-stream,application/pdf,application/x-pdf,application/vnd.pdf")
browser = webdriver.Firefox(firefox_profile=profile)

I also tried:

profile.set_preference("pdfjs.disabled", True)

However, Firefox does not automatically download the .pdf (even though it is application/pdf in the http req). Also, after I load that profile in Firefox, under "Options / Applications", the PDF format still shows "Preview in Firefox" instead of "Save File"... What am I doing wrong?

Try by adding the following preference also, to the existing list:

fp.setPreference("pdfjs.enabledCache.state", false);
fp.setPreference("browser.helperApps.neverAsk.openFile","application/pdf");

To disable open and download pdf in firefox:

FirefoxOptions options = new FirefoxOptions();
options.addPreference("browser.download.folderList", 2);
options.addPreference("browser.download.dir", pathToDownload);
options.addPreference("browser.helperApps.neverAsk.saveToDisk", "application/pdf");
options.addPreference("pdfjs.enabledCache.state",false); 
WebDriver driver = new FirefoxDriver(options);
