Adobe Flash in Selenium, Chrome 54.0.2840.59-1: "This plugin is not supported"

Installing flash player from https://get.adobe.com/flashplayer/ works for me on mac OS, note that you will need to install this on the chrome driver browser (not the chrome browser in your system). To do this, run your selenium test that opens the chrome and from there go to that URL ^ and follow install steps. After you are done, the next time you run the test it should pick up the change and should work.

@sircapsalot: it is possible and we do have automation for our app which is built in flash. It required that we add custom flex handlers which can then be called through javascript.

Linux: To get flash working on chrome 54, I took a working copy of the plugin file from my /usr/google-chrome, then I was able to use pass in a command line argument to chromedriver:

ClassLoader classLoader = getClass().getClassLoader(); File flashPath = new File(classLoader.getResource("libpepflashplayer.so").getFile());

ChromeOptions options = new ChromeOptions(); options.addArguments("--ppapi-flash-path=" + flashPath);

return new ChromeDriver(serviceBuilder.build(), options);

Windows: @user7038292's solution to install flash manually resolved the issue

Chrome 54 doesn't support Adobe Flash Player NPAPI anymore.So you just should install Adobe Flash Player PPAPI (from https://get.adobe.com/flashplayer/ ) on chrome browser in your system.
