Firefox Default Browser Agent

My Windows Task Scheduler contains an entry called "Firefox Default Browser Agent". If I delete it, it returns. If I disable it, it re-enables itself. Can't be modified either. How do I turn it off permanently?

I already have telemetry and automatic updates both turned off.

In about:config default-browser-agent.enabled is set to false

The Default Browser Agent scheduled task is not optional, the settings can disable functionality but not the task itself.

The list of reflected prefs includes the global telemetry opt-out pref datareporting.healthreport.uploadEnabled and a pref called default-browser-agent.enabled, which can enable or disable the entire agent. The agent checks these registry-reflected pref values when its scheduled task runs, they do not actually prevent the scheduled task from running.
