Probably not. The irony is that when you disable default browser features, sites can use this fact as a fingerprinting input, and it only makes your browser more unique.

I'd expect standard Firefox's protection + popular plugins to be good enough to reduce creepiness of everyday adtech. If you really don't like to be tracked, then the Tor browser may be a better bet. At least you'll look like every other Tor user, rather than stand out with your custom config and a niche-of-niches browser.
