selenium-server-4.0.0-alpha-3 - Firefox browser's default download path changing is not working

[Dinesh kumar]

The code for Firefox is:-

FirefoxProfile profile =new FirefoxProfile();

profile.setPreference("browser.download.folderList",2);

profile.setPreference("browser.download.dir","/Users/dinesh/Documents/");

profile.setPreference("browser.download.manager.showWhenStarting",false);

FirefoxOptions options = new FirefoxOptions();

options.setProfile(profile);

driver=new EventFiringWebDriver(new FirefoxDriver(profile));

I have gone through many Google answers but I found no solution for this issue.

Any help please?
