I am trying to download an application and check if it's downloaded into my local system or not. But when I click the download link I have a popup with Save or Cancel options, which is stopping me from downloading the file. I googled and found some solutions and tried to change the profile of Firefox by adding the below code, but it is not working.

firefoxProfile.setPreference("browser.download.folderList", 2);
firefoxProfile.setPreference("browser.download.alertOnEXEOpen", false);
firefoxProfile.setPreference("browser.helperApps.neverAsksaveToDisk", "application/x-msexcel,application/excel,application/x-excel,application/excel,application/x-excel,application/excel,application/vnd.ms-excel,application/x-excel,application/x-msexcel");
firefoxProfile.setPreference("browser.download.manager.showWhenStarting", false);
firefoxProfile.setPreference("browser.download.manager.focusWhenStarting", false);
firefoxProfile.setPreference("browser.helperApps.alwaysAsk.force", false);
firefoxProfile.setPreference("browser.download.manager.alertOnEXEOpen", false);
firefoxProfile.setPreference("browser.download.manager.closeWhenDone", false);
firefoxProfile.setPreference("browser.download.manager.showAlertOnComplete", false);
firefoxProfile.setPreference("browser.download.manager.useWindow", false);
firefoxProfile.setPreference("browser.download.manager.showWhenStarting", false);
firefoxProfile.setPreference("services.sync.prefs.sync.browser.download.manager.showWhenStarting", false);

This is the code I added for setting up Firefox preferences, but I still get the popup.

    This sounds like they either custom coded a popup dialog or are forcing the browser acknowledgement of it. Either way you should be able to execute a javascript to accept the dialog in the popup and close it. Do you have the rendered HTML?

I think you have missed some crucial options.

Please consider the code taken from this answer. Of course your MIME type will be different.

FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.download.dir", "C:\\Temp");  // folder
profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "video/mp4");  // MIME type
profile.setPreference("pdfjs.disabled", true);  // disable the built-in viewer
profile.setPreference("browser.download.folderList", 2);
profile.setPreference("browser.download.panel.shown", false);

DesiredCapabilities capabilities = DesiredCapabilities.firefox();
capabilities.setCapability(FirefoxDriver.PROFILE, profile);
capabilities.setCapability(CapabilityType.ELEMENT_SCROLL_BEHAVIOR, 1);

WebDriver driver = new FirefoxDriver(capabilities);

I've showed here how you can avoid any warning/pop-up while downloading any potentially harmful files like .exe, .jar etc in Chrome & Firefox (v113) using Selenium 4.9.1. Do the following:

HashMap<String, Object> chromePrefs = new HashMap<String, Object>();
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("prefs", chromePrefs);
