You can use Group Policy Object (GPO) to deploy the Webroot Web Threat Shield (WTS) extension to Firefox version 74 and later in Windows domains. To enable the WTS for a single computer, use these instructions.

Webroot has created this document to assist with using GPO to install the WTS extension. It assumes that you have experience with GPO and it is recommended that you do before proceeding. For more information on GPO from Microsoft, click here.

Webroot Support does not troubleshoot GPO and will not be able to answer GPO related questions. If the Web Threat Shield itself is malfunctioning in any way, Webroot Support will be able to investigate and assist.

To install the WTS to Firefox version 74 and later using GPO

  1. Download the latest Mozilla Policy templates from the Mozilla Policy templates site.
     

    Note: Click here for additional information on customizing Firefox using GPO.

  2. Unpack the files from the downloaded policy templates zip file.
     
  3. In the contents of the unpacked zip file, the Windows directory includes a firefox.admx and mozilla.admx file, in addition to a number of language directories. The language directories each contain a firefox.adml and mozilla.adml file. You will duplicate this structure when copying these files.
     
  4. Identify the language you will be using and place copies of the above files in the proper location:
     

    Note: The PolicyDefinitions folder will need to be created if it is not present.

     
    • If applying the GPO to a single computer
      1. Use location: C:\Windows\PolicyDefinitions
      2. Copy the firefox.admx and mozilla.admx files to C:\Windows\PolicyDefinitions
      3. Copy the firefox.adml and mozilla.adml files to the language directory located in C:\Windows\PolicyDefinitions
         
    • If applying the GPO to a domain
      1. Use location: \\<domain>\SYSVOL\<domain>\policies\PolicyDefinitions\
      2. Copy the firefox.admx and mozilla.admx files to C:\Windows\PolicyDefinitions
      3. Copy the firefox.adml and mozilla.adml files to the language directory located in \\<domain>\SYSVOL\<domain>\policies\PolicyDefinitions\
         

         
  5. Start the Group Policy Editor
    • To edit the policy for a single computer, open the Local Computer Policy by entering gpedit.msc at the Start menu.
    • To edit the policy for a domain, start Group Policy Management on a domain controller.
       
  6. You need to create a Group Policy Object (GPO) for the installation. In the left pane of the policy editor, under your local domain, go to Group Policy Objects, right click and select New.
     

     
  7. Provide a meaningful name, such as ‘Webroot Browser Extensions’. Once created, click the new policy and choose Edit…
     

     
  8. In the left pane of the policy editor, expand the tree structure and locate the Extensions to Install setting in the Firefox section:
    • Computer Configuration > Policies > Administrative Templates > Mozilla > Firefox > Extensions > Extensions to Install
       
  9. In the right pane, click Extensions to Install to open the Settings page and select Enabled.
     

     
  10. To specify the extension to install, click the Show button and add:
  11. As an optional step, you can prevent users from being able to uninstall extensions for FireFox. To do this:
    1. Locate the Prevent Extensions from being disabled or removed setting under Configuration > Administrative Templates > Mozilla > Firefox > Extensions
    2. Set a value of webrootsecure@webroot.com
