Troubleshooting Web Limiting

Troubleshooting Web Limiting

Overview

With LanSchool Air, teachers can help students focus on their work by limiting online access to approved websites and even disabling Internet access during tests and quizzes. LanSchool Air relies on the LanSchool Air Student client running on the student devices to enforce these policies. To support web limiting in most browsers, a companion browser extension is also required.

Who Should Use This Guide?

This article is designed to help IT Administrators troubleshoot instances where LanSchool Air Web Limiting is not being enforced. The LanSchool Air browser extension must be installed in each web browser in order to enforce the teacher's desired limiting policy.  The steps to troubleshoot this are different for each web browser.

Teachers should refer to this overview of how to setup and use web limiting for use in their classroom.

Troubleshooting Web Limiting

Check that the browser is on the latest version. If it is not on the latest version, update the browser if possible.

Google Chrome

Web limiting for the Google Chrome browser utilizes the LanSchool Air Chrome Extension. By default, this browser extension is installed as part of the student install on Windows and Mac devices, and deployed via Google Admin for Chromebooks.

Step 1: Confirm Extension Is Installed

  1. On a student device, open the Chrome browser and navigate to Settings > Extensions or enter chrome://extensions in the address bar. 
  2. Confirm that the LanSchool Air Chrome Extension is installed and enabled.
  3. If the extension is not installed, contact your IT team or proceed to Step 2

Step 2: Re-deploy the Extension If Required

By default, the LanSchool Air for Windows or macOS installer will attempt to automatically install the extension into Chrome. In some environments, this will fail if Chrome has not yet been installed or local policies require extensions be deployed another way. For Chromebook students, refer to Mass Deploying LanSchool Air for Chromebooks to deploy the Chromebook app and extensions.

Option 1 - Deploying Using Google Admin
Students will need to authenticate to the Chrome browser on their device in order for assigned extensions to be force-installed. To assign the LanSchool Air Chrome Extension to students so it is force-installed when they sign in, follow these steps.
  1. Login to Google Admin
  2. Navigate to Devices > Chrome > Apps & Extensions > User and Browser Settings
  3. Select the OU containing student user accounts
  4. Add an extension by extension ID
  5. In the Extension ID field, enter the following extension ID: baleiojnjpgeojohhhfbichcodgljmnj
  6. Ensure that the source is set to From the Chrome Web Store
  7. Click Save
  8. Set the Installation Policy to Force Install
  9. Click Save
Option 2 - Deploying Using Active Directory Group Policy (GPO)
If the LanSchool Air Student client fails to install the LanSchool Air browser extension, or if you have an existing list of force installed extensions in the Chrome browser, you may need to create/modify the following Group Policy to deploy the extension to student Windows devices:
  1. Open the Group Policy Management Console
  2. Navigate to User Configuration\Administrative Templates\Google\Google Chrome\Extensions (Chrome ADM/ADMX Templates Required)
  3. Go to "Configure the list of forced-installed apps and extension" and enable it
  4. Click the Show button
  5. Enter the following in an available line: baleiojnjpgeojohhhfbichcodgljmnj;http://clients2.google.com/service/update2/crx
  6. Deploy the policy, then refresh the Group Polices on the student machine



Mozilla Firefox

Web limiting for Firefox utilizes the LanSchool Air Web Helper browser extension. By default, this browser extension is installed as part of the student install on Windows and Mac devices. In some environments, this will fail if Firefox has not yet been installed or local policies require extensions be deployed another way.

Step 1: Confirm Extension Is Installed

  1. On a student device, open the Firefox browser and navigate to Settings > Add-Ons > Extensions or enter about:addons in the address bar. 
  2. Confirm that the LanSchool Air Web Helper extension is installed and enabled
  3. If the extension is not installed, contact your LanSchool IT Admin or proceed to Step 2.

Step 2: Deploy the Extension via Group Policy If Required

If the LanSchool Air client fails to install the LanSchool Air Web Helper browser extension, or if you have an existing list of force installed extensions in the Firefox browser, you may need to create/modify the following Group Policy to deploy the extension to student Windows devices:
  1. Open the Group Policy Management Console
  2. Navigate to \Software\Policies\Mozilla\Firefox\Extensions\ (Firefox ADMX Templates Required)
  3. Add the following Group Policy values:
    “Install” : “https://www.stonewarefiles.com/lsa/firefox/ffwebhelper.xpi
    “Locked” : “webhelperEd@lanschoolair.com"
  4. Deploy the new policy and perform a Group Policy update on the student devices
  5. Confirm that the LanSchool Air Web Helper browser extension was successfully installed
See Mozilla's documentation for other methods of deploying extensions using Intune, policies.JSON and other tools. If using policies.JSON, refer to this example file for the LanSchool Web Helper.



Microsoft Edge

Web limiting for the Microsoft Edge browser (Chromium-based, Version 85+) utilizes the LanSchool Air Web Extension for Edge. By default, this browser extension is installed as part of the student install on Windows and Mac devices.

Step 1: Confirm Extension Is Installed

  1. On a student device, open the Edge browser and navigate to Settings > Extensions.
  2. Confirm that the LanSchool Air Web Extension is installed and enabled.
  3. If the extension is not installed, contact your LanSchool IT Admin or proceed to Step 2.

Step 2: Deploy the Extension via Group Policy If Required

If the LanSchool student client fails to install the LanSchool Air Web extension for Edge, or if you have an existing list of force installed extensions in the Edge browser, you may need to create/modify the following Group Policy to deploy the extension to student Windows devices:
  1. Open the Group Policy Management Console.
  2. Navigate to User Configuration\Administrative Templates\Microsoft Edge\Extensions (Edge ADMX Templates Required)
  3. Go to "Control which extensions are installed silently" and enable it
  4. Click the Show button
  5. Enter the following extension ID: eiaojghieijbfokigddnebccjghkkbmg
  6. Deploy the new policy and perform a Group Policy update on the student devices.
  7. Confirm that the LanSchool Air Web extension was successfully installed.
