You have options to decline sending any potentially personal data back, and then telemetry would include only basic, anonymised usage info to help them improve Firefox. Pocket is now part of Mozilla and you can still just remove the button from the toolbar and ignore it completely. I assume that video chat thing was only ever proof-of-concept, at least I don't see it anywhere anymore. As for EME, well, most people want their Netflix/Hulu fix. If Mozilla declined to support EME then they'll quickly become obsolete.

This is unacceptable. Why can't I turn it off completely?

[Santosh83]

Seems like you can turn it off completely (except it still collects some data but does not actually send it to Mozilla), but you need to read the docs and toggle some about:config preferences.

Personally I'd just uncheck all the options exposed in the UI and trust that Mozilla is not collecting stuff behind my back, at least not data that can be de-anonymised.

I believe Santosh83 means even if you leave it on, it will be anonymized performance data

[brador]

You can't anonymize data in transit since it requires a sender IP which makes the sent performance data susceptible to interception and analysis by intermediaries.

It's boring data, encrypted in transit (HTTPS). About the only thing intermediaries can learn is that someone used Firefox at the time of the request.
