Block/Whitelist Chrome Extensions using Intune

This blog post will show how to block or whitelist Chrome extensions using Intune. This will give you greater control over which extensions can be used on your organization’s devices, helping to keep your data secure and your employees productive.

Allowing users to install extensions in browsers can pose a security risk. Users may unknowingly Install a malicious extension, which could cause Issues. Therefore, as Intune administrators, we should control the extensions allowed to be installed by end users.

A best practice is to block all extension installations and allow only specific extensions approved by the administrator. This way, you can ensure the extensions are safe and regularly updated.

If you manage your organization’s devices using Intune, you can create a device configuration profile with settings to allow and block extensions for Google Chrome and apply this profile to the target devices.

We’ll use the Google Chrome ADMX template settings to configure the block or whitelist of extensions. To create a Block list or Whitelist, you’ll need the Extension ID. Let’s follow the steps to find the Extension ID and then create the device configuration profile.

Block/whitelist Edge Extensions Using Intune

Step-by-Step Guide

Step 1 – Find the Extension ID that you want to Whitelist

To find the Extension ID in Chrome, follow the below steps:

  • Launch the Google Chrome browser.
  • Go to Google Webstore.
  • Search for the Extension that you want to whitelist, and then from the address bar of the browser, you can copy its Extension ID.

  • Repeat this process for any other extensions you wish to whitelist or block, copying their respective Extension IDs into a notepad for later use in the Intune device configuration policy.

Step 2 – Create a Device configuration profile

The next step is to create a device configuration profile in Intune. Let’s check the steps:

  • Sign in to the Intune admin center.
  • Go to Devices Configuration > Create > New Policy.
  • Select Platform as Windows 10 and later.
  • Profile type as Templates.
  • Click on Administrative Templates > Create.

If you are unable to Import Chrome ADMX template in Intune, you can refer to my other blog post, which provides a detailed, step-by-step guide on how to Import an ADMX file into Intune.


Basics Tab

Provide a Name and Description of the Policy and click Next.

Configuration Settings

  • Go to Computer Configuration > Google > Google Chrome > Extensions folder.
  • Search for the setting “Configure extension installation blocklist
  • Select the Enabled radio button.
  • Extension IDs the user should be prevented from installing: Add * in the text box, and then click OK to save.

Instead of blocking all extensions using a wild card character *. You can also provide the extension IDs to block only specific extensions in Chrome.

In this scenario, we are Blocking All Chrome Extensions and using Configure extension installation allow list setting to Whitelist specific Extensions.

  • Search for the setting “Configure extension installation allow list” and click on Enabled.
  • In the Extension IDs to exempt from the block list text box, provide one Extension ID per row that you want to Whitelist. In our example, we want to whitelist the Super Dark Mode extension, so we provided its extension ID. [Skip this step if you do not want to whitelist any Extensions in Google Chrome]

Click Add groups and select Entra security group containing Windows 10/11 devices or Entra ID users. Adding devices to the group and targeting them is recommended for a controlled deployment. Once testing proves successful, you can expand the deployment by including additional devices in the group.

Review + Create

Review the device configuration profile on the Review + Create tab and click Create.

Sync Intune Policies

The device check-in process might not begin immediately. If you’re testing this policy on a test device, you can manually kickstart the Intune sync from the device itself or remotely through the Intune admin center.

Alternatively, you can use PowerShell to force the Intune sync on Windows devices. Restarting the device is another way to trigger the Intune device check-in process.

End-user Experience

Let’s see how this policy affects the end user’s device. After successfully deploying this policy, open the Chrome browser to test whether the installation of all extensions is blocked and whether only the specific extension (in this case, Super Dark Mode) is allowed according to the whitelist.

If any existing extensions were installed when this policy was applied, they will also be blocked. Only the extensions that you whitelist from Intune will be allowed. An error may show up on Chrome: Blocked by admin. When you click this button, you will receive a pop-up message: Your admin has blocked <extension name> – App ID <app ID>.

In this blog post, we’ve explored a simple method for creating block lists and whitelists of extensions using Intune for the Chrome browser. You don’t need to utilize OMA-URI settings; instead, you can use Chrome ADMX settings to establish block lists and whitelists for Chrome extensions and apply them to end-user devices

  1. Chrome becomes total crap browser. Google has on New Chrome Web Store began to block all extensions install on chrome based browser (update to the last browser doesn’t help). Naked Chrome browser is USELESS (try to browse without any extensions installed).
