I use it alongside Firefox's built-in tracking protection for the embedded media placeholders.
(Sadly, it no longer auto-detects new trackers, because someone figured out how to track you using *that*, so it uses a pre-generated list now unless you *really* want to turn learning back on.)
We like the click-to-activate widget replacements too, but Privacy Badger is more than that: https://privacybadger.org/#Is-Privacy-Badger-compatible-with-Firefox%27s-built-in-content-blocking
