I think website blocker can work in privacy window too. Check the add-on setting.

Hello

Take a look at https://connect.mozilla.org/t5/ideas/block-websites-by-domain-list/idi-p/5643 policies.json

Try

{

 "policies": {
   "WebsiteFilter": {
     "Block": [
       "*://*.facebook.com/*",
       "*://*.instagram.com/*"
     ]
   }
 }

}

unfortunately no, as nothing saves when I close the privacy window

You can use a policies.json file to disable Private Browsing mode.

{
  "policies": {
    "DisablePrivateBrowsing": true
  }
}

Anya, this is true. You need to go to the Addons & Themes area (shortcut: Shift+Command+A), find your addon, click the small 3 dots "..." button for that addon then select "Allow" for the "Run in Private Windows" setting. That should force the website blocking addon to work in private mode. You may have to restart the browser after making that change but it usually takes effect immediately. The suggestions about policies.json are good too.
