I read that I could re-enable NPAPI in Chrome after Google decided to stop supporting these plugins (I suppose in order to force developers to embrace WebGL solutions) but the flag doesnt show up in the most recent version of Chrome (50.0.2661.94 m). Is it no longer possible enable NPAPI on Chrome?

1. 我了解到您遇到edge浏览器安装安全控件无效的问题。 应该是该控件不支持Edge引起的问题，请等待Windows后续更新的安装来修复该问题。 希望以上的信息可以帮助到您。.
2. Some browsers, such as Google Chrome and Mozilla Firefox, have removed support for the NPAPI plugin. Refer to following for the status of the NPAPI plugin support amongst browser versions: Google Chrome: NPAPI plugin support was disabled by default in version 42. NPAPI plugin support was removed in version 45 and later.
3. NPAPI plugins have been recently depreciated by most mainstream web browsers such as Google Chrome, Outlook, and Firefox. Currently, our team is pursuing a solution to this, however, as a primary means of accessing the web user interface for your Amcrest device, we recommend using either Internet Explorer or Safari.

WebDriver allows developers to create automated tests that simulate user interaction. WebDriver tests and simulations differ from JavaScript unit tests in the following ways.

• Accesses functionality and information not available to JavaScript running in browsers.
• Simulates user events or OS-level events more accurately.
• Manages multiple windows, tabs, and webpages in a single test session.
• Runs multiple sessions of Microsoft Edge on a specific machine.

The following section describes how to get started with WebDriver for Microsoft Edge (Chromium).

Install Microsoft Edge (Chromium)

Ensure you install Microsoft Edge (Chromium). To confirm that you have Microsoft Edge (Chromium) installed, navigate to edge://settings/help, and verify the version number is version 75 or later.

Download Microsoft Edge Driver

To begin automating tests, use the following steps to ensure that the WebDriver version you install matches your browser version.

1. Find your version of Microsoft Edge.

   1. Navigate to edge://settings/help.

2. Navigate to Microsoft Edge Driver.

3. Navigate to Get the latest version.

4. Choose the build of channel that matches your version number of Microsoft Edge.

   The Get the latest version section on the Microsoft Edge Driver webpage

Choose a WebDriver language binding

The last component you must download is a language-specific client driver to translate your code (Python, Java, C#, Ruby, JavaScript) into commands the Microsoft Edge Driver runs in Microsoft Edge (Chromium).

Download the WebDriver language binding of your choice. The Microsoft Edge team recommends Selenium 4.00-alpha07 or later, because it supports Microsoft Edge (Chromium). However, you may control Microsoft Edge (Chromium) in all older versions of Selenium, including the current stable Selenium 3 release.

Important

If you previously automated or tested Microsoft Edge (Chromium) using ChromeDriver and ChromeOptions classes, your WebDriver code does not run on Microsoft Edge Version 80 or later. To solve the problem, update your tests to use the EdgeOptions class and download Microsoft Edge Driver.

Use Selenium 3

If you already use Selenium 3, you may have existing browser tests and want to add coverage for Microsoft Edge (Chromium) without changing your version of Selenium. To use Selenium 3 to write automated tests for both Microsoft Edge (EdgeHTML) and Microsoft Edge (Chromium), install the Selenium Tools for Microsoft Edge package to use the updated driver. The EdgeDriver and EdgeDriverService classes included in the tools are fully compatible with the built-in equivalents in Selenium 4.

Use the following steps to add the Selenium Tools for Microsoft Edge and Selenium 3 to your project.

Add the Microsoft.Edge.SeleniumTools and Selenium.WebDriver packages to your .NET project using the NuGet CLI or Visual Studio.

Use pip to install the msedge-selenium-tools and selenium packages.

If your Java project uses Maven, copy and paste the following dependency to your pom.xml file to add msedge-selenium-tools-java.

The Java package is also available to download directly on the Selenium Tools for Microsoft Edge Releases page.

Use npm to install the edge-selenium-tools and selenium-webdriver packages.

Automate Microsoft Edge (Chromium) with WebDriver

To automate a browser using WebDriver, you must first start a WebDriver session using your preferred WebDriver language binding. A session is a single running instance of a browser controlled using WebDriver commands. Start a WebDriver session to launch a new browser instance. The launched browser instance remains open until you close the WebDriver session.

The following content walks you through using Selenium to start a WebDriver session with Microsoft Edge (Chromium). You may run the examples using either Selenium 3 or 4. To use with Selenium 3, the Selenium Tools for Microsoft Edge package must be installed.

Automate Microsoft Edge (Chromium)

Selenium uses the EdgeDriver class to manage a Microsoft Edge (Chromium) session. To start a session and automate Microsoft Edge (Chromium), create a new EdgeDriver object and pass it an EdgeOptions object with the UseChromium property set to true.

The EdgeDriver class only supports Microsoft Edge (Chromium), and doesn't support Microsoft Edge (EdgeHTML). For basic usage, you may create an EdgeDriver without providing EdgeOptions.

Note

If your IT admin has set the DeveloperToolsAvailability policy to 2, Microsoft Edge Driver is blocked from driving Microsoft Edge (Chromium), because the driver uses the Microsoft Edge DevTools. Ensure the DeveloperToolsAvailability policy is set to 0 or 1 to automate Microsoft Edge (Chromium).

Choose Specific Browser Binaries (Chromium-Only)

You may start a WebDriver session with specific Microsoft Edge (Chromium) binaries. For example, you may run tests using the Microsoft Edge preview channels such as Microsoft Edge Beta.

Customize the Microsoft Edge Driver Service

When you use the EdgeOptions class to create an EdgeDriver class instance, it creates and launches the appropriate EdgeDriverService class for either Microsoft Edge (EdgeHTML) or Microsoft Edge (Chromium).

If you want to create an EdgeDriverService, use the CreateChromiumService() method to create one configured for Microsoft Edge (Chromium). The CreateChromiumService() method is useful when you need to add customizations. For example, the following code starts verbose log output.

Note

You do not need to provide the EdgeOptions object when you pass EdgeDriverService to the EdgeDriver instance. The EdgeDriver class uses the default options for either Microsoft Edge (EdgeHTML) or Microsoft Edge (Chromium) based on the service you provide.
However, if you want to provide both EdgeDriverService and EdgeOptions classes, ensure that both are configured for the same version of Microsoft Edge. For example, you may use a default Microsoft Edge (EdgeHTML) EdgeDriverService class and Chromium properties in the EdgeOptions class. The EdgeDriver class throws an error to prevent using different versions.

When you use Python, the Edge object creates and manages the EdgeService. To configure the EdgeService, pass extra arguments to the Edge object as indicated in the following code.

Use the createDefaultService() method to create an EdgeDriverService configured for Microsoft Edge (Chromium). Use Java system properties to customize driver services in Java. For example, the following code uses the 'webdriver.edge.verboseLogging' property to turn on verbose log output.

When you use JavaScript, create and configure a Service with the ServiceBuilder class. Optionally, you may pass the Service object to the Driver object, which starts (and stops) the service for you.
To configure the Service, run another method in the ServiceBuilder class before you use the build() method. Then pass the service as a parameter in the Driver.createSession() method.

Use Chromium-Specific Options

If you set the UseChromium property to true, you may use the EdgeOptions class to access the same Chromium-specific properties and methods that are used when you automate other Chromium browsers.

Note

If the UseChromium property is set to true, you are not able to use properties and methods for Microsoft Edge (EdgeHTML).

Symptoms

Consider the following scenario:

• Google Chrome is configured as your default browser.
• Your Google Chrome installation is upgraded to version 42 or a later version.
• You try to join a meeting by clicking a 'Join Lync Meeting' or 'Join Skype Meeting' link, and any one of the following criteria are true:

  • You click the link within any application other than Microsoft Outlook 2013.

  • The meeting organizer did not create the meeting by using the Outlook Lync or Skype for Business meeting plugin.

  • The meeting organizer is from another organization that has not configured the option to preserve the Transport Neutral Encapsulation Format (TNEF) for outgoing email messages. For more information, go to the following Outlook website:

In this scenario, when you click the 'Join Lync Meeting' or 'Join Skype Meeting' link, you expect the locally installed Lync or Skype for Business client to start. Instead, the default web browser starts and you are directed to the Lync Web App or Skype for Business Web App webpage. Then, you are prompted to install a plugin or you are joined to the meeting by using the web experience.

Cause

This problem occurs because, by default, the updated version of Google Chrome deprecates and disables support for the Netscape Plugin API (NPAPI). NPAPI is currently used as part of the client detection process for the Lync or Skype for Business client when you join a meeting by clicking a link. When NPAPI is disabled, the webpage cannot determine whether you have the client installed.

Resolution

May 2015 cumulative update (5.0.8308.887) for Microsoft Lync Server 2013 that enables Mac users and Windows users to join a meeting by using Lync Web App in any default browser that you set. It does not require to use NPAPI to join a meeting if Chrome is the default browser. See the following article for more information:

Workaround

Activar Npapi Edge

To work around this problem, use one of the following methods.

Option 1: Change the default browser

Npapi Edge Plugin

2. Install the GPO policy templates by using the following directions:

3. Configure the 'Computer ConfigurationAdministrative TemplatesGoogleGoogle ChromeContent SettingsAllow plugins on these sites' setting by enabling the policy and by configuring the list of meeting join domain URLs that should be trusted.

   Note

   This list should contain the following items:

   • The meeting join URL of the user's organization.
   • The URLs of any business partners that members of the user's organization frequently join in meetings.
   • The default Lync and Skype for Business online meeting URL.
