How to disable Chrome Plugins in Selenium WebDriver using Java

Question

Chrome Plugin pop up

When I am executing my Automation Code for this application the above popup is displayed. Now I would need to know how to disable PDF Viewer Plugin in Selenium WebDriver using Java.

Here's what I am using right now which is not working.

 DesiredCapabilities capabilities = DesiredCapabilities
                                .chrome();
                        ChromeOptions options = new ChromeOptions();
                        options.addArguments(new String[] { "test-type" });
                        options.addArguments(new String[] { "disable-extensions" });


String pluginToDisable = "Chrome PDF Viewer";
                        options.addArguments("plugins.plugins_disabled", pluginToDisable);


                        capabilities.setCapability("chrome.binary",
                                chromeDriver.getAbsolutePath());
                        capabilities.setCapability(ChromeOptions.CAPABILITY,
                                options);
                        options.addArguments("--lang=en-gb");
                        GlobalVars.driver = new ChromeDriver(capabilities);

Updated for Chrome V: 57

This solution is no longer working.

Here is a valid implementation in C#:

        var options = new ChromeOptions();
        // This was a PAIN. If this ever does not work, here is how I got the preference name:
        // 1. Navigate to : chrome://settings/content
        // 2. Scroll to the bottom "PDF Documents" section
        // 3. Right-Click and inspect element on the check box titled "Open PDF files in the default PDF viewer application"
        // 4. The preference name is the pref key for the input, in this case: pref="plugins.always_open_pdf_externally"
        options.AddUserProfilePreference("plugins.always_open_pdf_externally", true);

        // The constructor must be pointed to the chrome driver .exe
        // Or you must set a PATH variable pointing to the location
        using (var driver = new ChromeDriver(options))
        {
        ..........
