“Mildew King” sounds like a boss in Dark Souls / Elden Ring / etc.

As you suggested, I suspect it’s the rare combination of additional extensions that’s contributing to your uniqueness in a fingerprinting sense.

Firefox’s built in “Enhanced Tracking Protection” already does a lot of this work for you, especially if you select “strict mode.” Go ahead and try this extension if you prefer. But remember to be selective with the extensions you add to your browser in general, as they also present an opportunity to introduce vulnerabilities.
