Selenium Firefox Preference for opening downloaded files

I've been looking for a way to download and run a JNLP file when using Selenium and Firefox. In the Firefox browser, I have the setting as shown in the screenshot below, so that the JNLP file downloads and runs without any popups.

Is it possible to replicate this is with FireFox Profile? I have the following set up, but it only downloads the file, it isn't automatically opening the file:

void setFireFoxDriverProperty(){         System.setProperty("webdriver.gecko.driver","C:\\TestAutomation\\selenium_drivers\\geckodriver.exe")        FirefoxProfile profile = new FirefoxProfile()      profile.setPreference("browser.download.folderList", 2)      profile.setPreference("browser.download.manager.showWhenStarting", false)      profile.setPreference("browser.download.dir", "c:\\temp")      profile.setPreference("browser.helperApps.neverAsk.saveToDisk", "application/x-java-jnlp-file")      profile.setPreference("browser.helperApps.neverAsk.openFile", "application/x-java-jnlp-file")        FirefoxOptions options = new FirefoxOptions()      options.setProfile(profile)      driver = new FirefoxDriver(options)  }
