Installing the Nexthink browser extension

The monitoring of web applications relies on a browser extension available for Google Chrome, Microsoft Edge, and Mozilla Firefox.

The Nexthink browser extension is available on the Chrome web store and Microsoft Edge add-ons repository. Nexthink directly hosts the extension for Firefox.

Chrome

Google Web Store with miinajhilmmkpdoaimnoncdiliaejpdk as extension ID

Edge

Microsoft Edge add-ons repository with higleibocjmgcnbikjneplkibiopjnkp as add-on ID

Firefox

Direct download from Nexthink with {393c57f8-28d9-11eb-8f58-3b6871335926} as extension ID

Deployment considerations

Deployment pace varies and depends on the release process of your organization. For any change in hardware or software, the implementation of the browser extension should be preceded by a proof of concept and testing phase. This is typically done on a limited number of endpoints.

Additionally, you should ensure that the Nexthink browser extension is a part of their browser policy, which enforces the extension.

You can use a dedicated remote action to deploy the extension. For a new environment, you can deploy it through Collector. This offers convenience and speed of deployment on a small set of devices but is not recommended as it can conflict with existing policies.

The remote action, or the Collector installation, installs the browser extension by setting a registry key at the local machine level which can overwrite any existing browser extension policies at the current user level.

To check your existing policies on a device, type chrome://policy in the Chrome address bar or edge://policy for Edge.

For more information about policy management, refer to your browser documentation:

• Understand Chrome policy management

• Configure Microsoft Edge policy settings on Windows

• Customizing Firefox Using Group Policy

Before rolling out the extension to the whole organization, you should run a campaign using Nexthink Engage to communicate to the employees about deployment. Explain that only listed domains are monitored, and this can be verified at any time with the tooltip of the extension icon.

Download a template campaign as a library pack for a quick start.

Installation

Policies

Using a Group Policy Object (GPO) or policy profiles, your IT department can deploy the browser extension.

Windows

In case the extension is not deployed through GPOs on Windows, please verify that there is no existing policy that could remove the extension or prevent NativeMessaging communication.

Collector Installer

Windows

You can deploy the Nexthink browser extension for Chrome, Firefox and Edge at the same time Collector is installed. For this purpose, you must enable the install_browser_extension flag of the Collector MSI installer. The Collector installer generator also includes a tick box to set this option. Similarly, the install_browser_extension flag has a disable value which removes the browser extension when set to this value.

The Collector installer generator tick box only installs the browser extension if checked and does not uninstall the browser extension if not checked.

Collector configuration tool (nxtcfg)

Windows

You can use the Collector configuration tool utility to force install and lock the Nexthink browser extension for Chrome, Firefox, and Edge browsers. The tool deploys the browser extensions using registry keys.

The install_browser_extension flag with the enable value forces the installation of the Nexthink browser extensions. The following command must be run with admin rights:

nxtcfg.exe /s install_browser_extension=enable

To uninstall the browser extensions, set the install_browser_extension flag to the disable value.

nxtcfg.exe /s install_browser_extension=disable

Remote Actions

Use Nexthink Act to facilitate the deployment of the Nexthink browser extension. The remote action scripts developed by Nexthink deploy all the necessary registry keys.

Windows

The following remote action deploys the Applications extension for all 3 browsers:

• Set Applications

It does not restart the browser and is not associated with a Nexthink Engage campaign. The same remote action is also capable of disabling the extensions.

Other remote actions are available for a specific browser:

• Google Chrome

• Microsoft Edge

• Mozilla Firefox

These remote actions restart the browser and send employees a Nexthink Engage campaign to notify them of the change.

macOS

The following remote action helps you get the list of extensions for a specific browser and check the browser extension status:

• Chrome Browser Management

• Firefox Browser Management

• Get Nexthink browser extension status

Monitoring deployment progress

You can monitor the deployment progress with the dedicated Applications - Browser Extension Management dashboard provided through Nexthink Library. This dashboard also let you monitor the health and status of your Nexthink browser extensions to ensure you are receiving the most accurate results from the Applications module.

Browser extension admin mode

You can access the browser extension admin mode to test transactions in real-time on an endpoint and to view all the data collected by the extension.

To activate the admin mode:

• Select the Nexthink browser extension from the list of extensions.

• A pop-up appears indicating whether your experience on the current page is being optimized or not. You can access the admin mode only on web pages monitored by the extension. A blue Nexthink Logo indicates that the web page is being monitored.

• Click five times on Powered by to activate the admin mode.

Admin mode eliminates the need to use browser developer tools to test transactions and still works when the Transaction end option is set to be detected automatically.
