  Use the FoxFilter Script   Do it Myself

Step 1: Download the Helper Script

Download the helper script to your computer. This is a small, free file that applies the browser policies to all your browsers at once.

Step 2: Run It

What you'll see:

  IMPORTANT:

  This tool modifies browser settings using administrator
  privileges. It is not foolproof and may be bypassed or
  reversed.

  Use at your own risk. This tool is not a substitute for
  supervision or administrative controls.

  FoxFilter Helper Script
 ========================================================

  Choose an option:

    1.  Lock FoxFilter    (prevent removal)
    2.  Unlock FoxFilter  (allow removal)
    3.  Check Status
    4.  Exit

  Enter your choice (1-4): 1

  Locking FoxFilter to prevent removal...

  [Chrome]  Locked.
  [Edge]    Locked.
  [Firefox] Locked.

  Done! Please restart any open browsers for
  the changes to take effect.

Good to Know

• After applying, Chrome and Edge will show "Managed by your organization" in the browser menu. This is normal and simply means a browser policy is active.
• Works across Chrome, Edge, and Firefox on both Windows and Mac.
• To reverse the changes later, run the script again and choose option 2.
• You can also choose option 3 to check the current status of each browser.

You can apply the same browser policies manually without using the helper script. These are standard settings used by IT administrators to manage browser extensions.

Important: All steps below require administrator privileges. Restart your browsers after making changes.

Windows — Chrome & Edge

Open Registry Editor (regedit) as Administrator and create the following keys and values:

Chrome

Policy Location
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Chrome\ExtensionInstallForcelist

1. Navigate to (or create) the registry key above.
2. Create a new String Value named 1
3. Set its data to:

nopeodilnmhhlfageeohjojginlgeljk;https://clients2.google.com/service/update2/crx

Edge

Policy Location
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Edge\ExtensionInstallForcelist

1. Navigate to (or create) the registry key above.
2. Create a new String Value named 1
3. Set its data to:

pfbgokdillfdcimbbbbmlhpdinmmmogf;https://edge.microsoft.com/extensionwebstorebase/v1/crx

Note: If other extensions already use value name 1, use the next available number (e.g. 2, 3, etc.).

Windows — Firefox

1. Find your Firefox installation folder (usually C:\Program Files\Mozilla Firefox).
2. Inside it, create a folder called distribution if it doesn't already exist.
3. Inside distribution, create a file named policies.json with the following content:

{
  "policies": {
    "Extensions": {
      "Install": ["https://addons.mozilla.org/firefox/downloads/latest/foxfilter/latest.xpi"],
      "Locked": ["foxfilter@inspiredeffect.net"]
    },
    "ExtensionSettings": {
      "foxfilter@inspiredeffect.net": {
        "installation_mode": "force_installed",
        "install_url": "https://addons.mozilla.org/firefox/downloads/latest/foxfilter/latest.xpi"
      }
    }
  }
}

Both the legacy Extensions format (Firefox 60+) and the modern ExtensionSettings format (Firefox 69+) are included for maximum compatibility.

Mac — Chrome & Edge

Open Terminal and run the following commands with sudo:

Chrome

sudo defaults write "/Library/Managed Preferences/com.google.Chrome" \
  ExtensionInstallForcelist -array-add \
  "nopeodilnmhhlfageeohjojginlgeljk;https://clients2.google.com/service/update2/crx"

Edge

sudo defaults write "/Library/Managed Preferences/com.microsoft.Edge" \
  ExtensionInstallForcelist -array-add \
  "pfbgokdillfdcimbbbbmlhpdinmmmogf;https://edge.microsoft.com/extensionwebstorebase/v1/crx"

Mac — Firefox

1. Open Terminal and create the distribution folder:
   sudo mkdir -p "/Applications/Firefox.app/Contents/Resources/distribution"
2. Create the policies file:
   sudo nano "/Applications/Firefox.app/Contents/Resources/distribution/policies.json"
3. Paste the same policies.json content shown in the Windows — Firefox section above, then save and exit.

Good to Know

• After applying, Chrome and Edge will show "Managed by your organization" in the browser menu. This is normal and simply means a browser policy is active.
• Works across Chrome, Edge, and Firefox on both Windows and Mac.
• The distribution folder may not exist by default — you'll need to create it.
• Firefox updates can sometimes delete the distribution folder, requiring the policy to be reapplied.
• Firefox reads policies.json only at startup — a full restart is required after changes.
• You can verify Firefox policies are active by visiting about:policies in the browser.

To Reverse (Unlock)

• Windows (Chrome/Edge): Delete the FoxFilter entry from the registry key, or delete the entire ExtensionInstallForcelist key if FoxFilter is the only entry.
• Mac (Chrome/Edge): Run sudo defaults delete "/Library/Managed Preferences/com.google.Chrome" ExtensionInstallForcelist (same pattern for Edge).
• Firefox (all platforms): Delete the policies.json file from the distribution folder.
