Firefox for Android has issues playing back YouTube video through my car stereo and some other types of speakers. Specifically, it works fine with my headphones but not through my car.

Chrome, YouTube app, and other browsers don't have this issue and my car is fine otherwise. I've had this issue on 3 different phones from 2 different manufacturers on multiple versions of Firefox for years and the issue comes and goes with updates but it has been an issue for the past few months now, so I know it's Firefox and not Android or my phones.
