Firefox doesn't care about your privacy. They implemented the same bloated information-leaking APIs like AudioContext that Google did. These APIs are used almost exclusively for tracking.
Coupled with their recent pro-deplatforming stance, Firefox's death will accelerate and it's a good thing. Mozilla has been consumed by greed (Google deal), incompetence (Firefox mobile) and politics ('deplatform our ideological enemies' blogpost).
It's not that black and white. Without APIs people would complain about bad support. Without the Google deal Mozilla would no longer exist. And really, all it is is one little setting you can change once and for all after you install it.
Just to be clear, there is no valid reason for AudioContext to leak audio latency information without the user's permission. It is used almost exclusively for ad tracking and fingerprinting.
On sites that do not ever play audio, the browser leaks sensitive highly personalized audio information to any ad network that wants it. That's not a 'feature', it's a spyware backdoor for ad networks.
Even if Mozilla/Firefox dies I'd like to believe its spirit and rendering engine will live on in forks. Maybe we'll have another successor to Firefox as Firefox was to Netscape.
