Disabling flash in Chrome

Question

One of our internal applications has a flash object on a page. I need to test one of the corner cases when there is no flash plugin available/installed in the browser: n

Answer 1

Found it, there is an another switch which tells chrome not to load external plugins at all:

--disable-plugins-discovery Disable discovering third-party plug-ins. Effectively loading only ones shipped with the browser plus third-party ones as specified by --extra-plugin-dir and --load-plugin switches.

By combining --disable-internal-flash and --disable-plugins-discovery I've achieved disabling all flash plugins in Chrome.

Answer 2

To disable Flash Player, type:

chrome:plugins

Into your URL bar. There you will see a list of all your plugins, including Flash Player. Press the button that says disable and you are good to go!

Answer 3

chrome://plugins doesn't exist anymore in Chrome 57 and above. Method proposed by alecxe in accepted answer unfortunately doesn't work for me.

I was able to workaround this issue by turning on mobile emulation on ChromeDriver. Example code for some languages can be found here: https://sites.google.com/a/chromium.org/chromedriver/mobile-emulation

Example code for java from the above page:

Map<String, String> mobileEmulation = new HashMap<String, String>();
mobileEmulation.put("deviceName", "Google Nexus 5");

Map<String, Object> chromeOptions = new HashMap<String, Object>();
chromeOptions.put("mobileEmulation", mobileEmulation);
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
WebDriver driver = new ChromeDriver(capabilities);

You can also specify your own screen resolution, pixel ratio and even userAgent.

Map<String, Object> deviceMetrics = new HashMap<String, Object>();
deviceMetrics.put("width", 1920);
deviceMetrics.put("height", 1080);
deviceMetrics.put("pixelRatio", 1.0);

Map<String, Object> mobileEmulation = new HashMap<String, Object>();
mobileEmulation.put("deviceMetrics", deviceMetrics);
mobileEmulation.put("userAgent", "Mozilla/5.0 (Linux; Android 4.2.1; en-us; Nexus 5 Build/JOP40D) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166 Mobile Safari/535.19");

Map<String, Object> chromeOptions = new HashMap<String, Object>();
chromeOptions.put("mobileEmulation", mobileEmulation);
DesiredCapabilities capabilities = DesiredCapabilities.chrome();
capabilities.setCapability(ChromeOptions.CAPABILITY, chromeOptions);
WebDriver driver = new ChromeDriver(capabilities);

This will work with RemoteWebDriver also.
