Cookie Auto-Delete Doesn't Work in Waterfox or Firefox

The about:config setting for privacy.firstparty.isolate collides with Cookie Auto-Delete and prevents it from working. Setting it to false regains Cookie Auto-Delete's capabilities.

Noscript/Firefox > This is a privileged page, whose permissions cannot be configured.

On Firefox 60 ESR, I first ran into this garbage:

This is a privileged page, whose permissions cannot be configured.

To get rid this nuisance, modify about:config settings:

about:config

Create the following boolean if it doesn't exist:

• Right-click in a vacant space > New > boolean
• Enter preference name: bash privacy.resistFingerprinting.block_mozAddonManager

Enter boolean value:

• Select true

Also empty the following (choose yourself what to whitelist):

extensions.webextensions.restrictedDomains

---

This appears to be a "hidden" setting meant for Tor, according to the extensions API:

static bool IsValidHost(const nsACString& host) {
  // This hidden pref allows users to disable mozAddonManager entirely if they
  // want for fingerprinting resistance. Someone like Tor browser will use this
  // pref.
  if (Preferences::GetBool(
          "privacy.resistFingerprinting.block_mozAddonManager")) {
    return false;
  }
