Group Policy Deployment - Firefox

Deploying KeeperFill via Group Policy

Deploying Keeper Firefox Browser Extension via Group Policy Management

This section describes how to utilize your Active Directory Group Policy Management, against Firefox Policy Templates, to deploy the Keeper Browser extension to all PCs in your organization. Please note this is a general guide.

Step 1: Adding Firefox Policy Templates

On your domain controller, download the zip file and extract the Firefox Policy Template file to your desired location. Ex: C:\temp

Step 2: Adding Firefox .admx and .adml files to Group Policy

  1. 1.
    Navigate to the directory in which you extracted the Firefox Policy Template file and copy the firefox.admx file located within the \policy_templates_v.(version)\windows directory to C:\Windows\PolicyDefinitions
  2. 2.
    Navigate to the directory in which you extracted the Firefox Policy Template file and copy the firefox.adml file located within the \policy_templates_v.(version)\windows\en-US directory to C:\Windows\PolicyDefinitions\en-US
NOTE: If a different language is desired instead of en-US, please navigate to the directory for the correct language of your choosing. Ex: es-ES

Step 3: Create or Configure your Firefox Policy

  1. 1.
    Open Group Policy Manager on your domain controller and expand out your domain -> Group Policy Objects. If you currently do not have a Group Policy created in which you want to utilize for Firefox Policies, proceed to right clicking on Group Policy Objects and create a New Policy.

If you have more than one OU (Organizational Unit) that you would like to Link this new Group Policy to, repeat steps 12 - 13.
For any PC within that OU, the “Firefox Policy” will automatically install the Keeper Security Browser Extension, if Firefox is installed on those PCs as well as disable Firefox's, less secure, built-in password manager and AutoFill capabilities.

Step 4: Check Your Firefox Policies

On a target client device, open Firefox and navigate to about:policies to see all policies that are applied. If you applied policy settings on the local computer, policies should appear immediately.
