I developed a crawler with ruby watir-webdriver that downloads some files from a page. My problem is that when I click to download the second file, Chrome opens a bar in the

I'm using Chrome 49 and none of the other solutions worked for me. After some research I found a working solution:

ChromeDriver createChromeDriverWithDownloadFolder(String folder) {
    Map chromePrefs = new HashMap();
    chromePrefs.put("profile.default_content_settings.popups", 0);
    chromePrefs.put("download.default_directory", folder);
    chromePrefs.put("profile.content_settings.exceptions.automatic_downloads.*.setting", 1 );
    chromePrefs.put("download.prompt_for_download", false);

    ChromeOptions options = new ChromeOptions();
    options.setExperimentalOption("prefs", chromePrefs);
    DesiredCapabilities cap = DesiredCapabilities.chrome();
    cap.setCapability(CapabilityType.ACCEPT_SSL_CERTS, true);
    cap.setCapability(ChromeOptions.CAPABILITY, options);
    return new ChromeDriver(cap);
}

It seems as if these settings are constantly changing. Therefore, here's how I found the right solution for my setup:

1. Open Chrome and go to chrome://version/ to find the path of your profile

2. In Default/Preferences is a json file called Preferences. Open it and search for automatic_downloads. In my case the interesting part of the file looked like this:

   ..."profile": { "avatar_bubble_tutorial_shown": 1, "avatar_index": 0, "content_settings": { "clear_on_exit_migrated": true, "exceptions": { "app_banner": {}, "auto_select_certificate": {}, "automatic_downloads": { "[.]localhost:63342,": { "setting": 1 },...

3. From that I could derive that the right setting would be chromePrefs.put("profile.content_settings.exceptions.automatic_downloads.*.setting", 1 );
