FYI if you want to edit the Firefox policies directly and save it in /etc/firefox/policies/policies.json, this is the file they are using

  "policies": {
    "DisableFirefoxStudies": true,
    "DisableTelemetry": true,
    "DontCheckDefaultBrowser": true,
    "FirefoxHome": {
      "SponsoredStories": false,
      "SponsoredTopSites": false,
      "Stories": false
    },
    "GenerativeAI": {
      "Enabled": false
    },
    "SearchEngines": {
      "Remove": [
        "Perplexity"
      ]
    }
  }
}`

AI slop

Certainly a more accurate descriptor.
