⚠️ CRITICAL: Install policies.json for Maximum Protection

The extension alone is NOT enough! Without the policies.json file, tech-savvy users can easily bypass protection by accessing about:addons,
about:config, Developer Tools, or Private Browsing mode.

📁 How to Install policies.json

🪟 Windows
1. Navigate to C:\Program Files\Mozilla Firefox\ (or C:\Program Files (x86)\Mozilla Firefox)
2. Create a folder called distribution (if it doesn't exist)
3. Inside the distribution folder, create a new file called policies.json
4. Copy and paste the code below into the file and save
5. Restart Firefox

🍎 macOS
1. Navigate to /Applications/Firefox.app/Contents/Resources/
2. Create a folder called distribution (if it doesn't exist)
3. Inside the distribution folder, create a new file called policies.json
4. Copy and paste the code below into the file and save
5. Restart Firefox

🐧 Linux
1. Navigate to /usr/lib/firefox/ or /usr/lib64/firefox/
2. Create a folder called distribution (if it doesn't exist)
3. Inside the distribution folder, create a new file called policies.json
4. Copy and paste the code below into the file and save
5. Restart Firefox

📄 policies.json Code

{
"policies": {
"BlockAboutAddons": true,
"BlockAboutConfig": true,
"BlockAboutProfiles": true,
"BlockAboutSupport": true,
"DisableDeveloperTools": true,
"DisablePrivateBrowsing": true,
"DisableSafeMode": true,
"DisableProfileRefresh": true,
"DisableProfileImport": true,
"InstallAddonsPermission": {
"Default": false
},
"Preferences": {
"devtools.policy.disabled": true,
"browser.privatebrowsing.autostart": false
}
}
}

🛡️ What policies.json Blocks
  • ❌ about:addons - Prevents extension removal
  • ❌ about:config - Prevents settings tampering
  • ❌ Developer Tools - Prevents code inspection/bypass
  • ❌ Private Browsing - Completely disabled at browser level
  • ❌ Safe Mode - Prevents bypassing extensions
  • ❌ Installing new add-ons - Prevents installing bypass tools
  • ❌ Profile import/refresh - Prevents resetting to bypass
To verify: Visit about:policies - you should see the policies listed as "Active".Note: policies.json requires administrator/root access to install and provides system-level protection that cannot be bypassed by the user.

⚠️ Without policies.json, your protection can be bypassed in seconds!
