Not quite for me - Fennec (at least the build from F-droid) does not randomize fingerprint, AppManager and TrackerControl both show it has embedded trackers sending telemetry to Mozilla, and Fennec is not available on desktop. Librewolf is hardened Firefox on desktop, and is very good though, and has the trackers going back to Mozilla removed, but it does not randomize fingerprint.
