Microsoft Edge (Chromium)允许安装扩展，但要在 Edge 中安装浏览器扩展^{(install browser extensions in Edge)}，您必须访问Windows Store。在某些情况下，您可能希望不是从Windows 应用商店^{(Windows Store)}而是从其他地方安装扩展程序。Edge浏览器支持此功能。

此外，如果您是开发人员并且想要测试新扩展，则必须从Windows 应用商店外部加载^{(Windows Store)}Edge浏览器扩展。但是，您需要启用扩展开发人员功能。Microsoft Edge允许旁加载（安装和运行未经验证的扩展）。Microsoft WebDriver支持在Microsoft Edge会话中自动加载扩展。  WebDriver是一个平台和语言中立的界面，使开发人员能够创建自动化测试。

^(Install)从Windows^(Windows) Store外部安装并启用Edge扩展

尽管Edge允许从^(Edge)Microsoft Store外部安装扩展，但它并不喜欢它们。带有以下描述的消息证实了这一点 -想要增强您的浏览器体验？尝试从 Microsoft Store 添加扩展^{(Want to enhance your browser experience? Try adding extensions from the Microsoft Store)}。

1]来自Windows应用商店外部的Sideload Edge浏览器扩展

打开 Microsoft Edge 并在地址栏中键入“ about:flags ”。

选中“启用扩展开发人员功能” ^{(Enable extension developer features’ )}复选框。

转到“设置和更多^{(Settings and more)}”菜单（...）将其打开。

从菜单中选择“扩展”  ，然后点击^{(Extensions’ )}“加载扩展”^{(‘Load extension’)} 按钮。

导航^(Navigate)到扩展程序的文件夹并选择“选择文件夹”^{(‘Select folder’)} 按钮。

您现在应该会在 Microsoft Edge 的扩展窗格中看到该扩展。

2]从Chrome Web Store安装 Edge^{(Install Edge)}浏览器扩展

转到设置和更多^{(Settings and more)}'菜单（...）。

选择“扩展^(Extensions)”。

在这里，您会在底部找到 2 个选项 -

• 开发者模式
• 允许来自其他商店的扩展程序

通过切换开关启用第二个选项。然后，要添加扩展程序，只需搜索扩展程序并点击“添加到 Chrome^{(Add to Chrome)} ”按钮。

出现提示时，单击“添加扩展”^{(‘Add extension’)}。

应该安装扩展没有任何问题。请务必仅从您完全信任的来源加载扩展，以免最终损害您的 Windows 计算机。

选择并加载扩展后，再次重新启动Edge浏览器。

How to install Edge browser extension from outside Windows Store

Microsoft Edge (Chromium) allows the installation of extensions but to install browser extensions in Edge, you have to visit the Windows Store. There can be instances where you might want to install extensions not from Windows Store but elsewhere. Edge browser supports this capability.

Also, if you are a developer and would like to test new extensions you’ll have to sideload Edge browser extension from outside the Windows Store. However, you’ll be required to enable extension developer features. Microsoft Edge allows sideloading (installation and running unverified extensions). Microsoft WebDriver supports the automated side loading of extensions in Microsoft Edge sessions.  WebDriver is a platform and language-neutral interface that enables developers to create automated tests.

Install & enable Edge extension from outside Windows Store

Although Edge allows installing extensions from outside Microsoft Store, it does not prefer them. A message bearing the following description confirms it – Want to enhance your browser experience? Try adding extensions from the Microsoft Store.

1] Sideload Edge browser extension from outside Windows Store

Open Microsoft Edge and type ‘about:flags‘ into the address bar.

Select the ‘Enable extension developer features’ checkbox.

Go to ‘Settings and more‘ menu(…) to open it.

Select ‘Extensions’ from the menu and hit the ‘Load extension’ button.

Navigate to your extension’s folder and choose the ‘Select folder’ button.

You should now see the extension listed in Microsoft Edge’s extension pane.

2] Install Edge browser Extensions from Chrome Web Store

Go Settings and more‘ menu(…).

Select ‘Extensions‘ .

Here, you will find 2 options visible at the bottom-

• Developer mode
• Allow extensions from other store

Enable the second option by toggling the switch. Then, to add an extension, simply search for the extension and hit ‘Add to Chrome‘ button.

When prompted, click ‘Add extension’.

The extensions should be installed without any problem. It is important that you load extensions only from sources that you trust completely, lest you end up compromising your Windows computer.
