FxR used to have telemetry based on glean. We disabled that long time ago and haven't sent any telemetry information to any server since almost the very beginning. However it's very important for us knowing which features of the browser are mostly used in order to focus our scarce resources on those important areas.
We've chosen the OpenTelemetry API because it's flexible enough to support simple use cases (like Wolvic) while being able to be customized at will.
This initial implementation does not send anything to any server yet, it's logging everything to the device logcat but it's the basis for future works.
