If you are downloading the tarball from Mozilla, then you are affected by this telemetry:

I don't think that's the case; the telemetry is part of the installer, not the installed binary (that the tarball would contain)

The article says the download id is transmitted to Mozilla on first run, so it must be part of the installed binary?

However, the article does say the Mozilla FTP site doesn't have the download id.
