Mozilla collects a limited set of aggregate data by default, but it can be opted out. Users can also opt in to send a more extensive data set (also aggregate AFAIK), but that's not the default.

The screen shot from your preferences section is odd - all the boxes are there on Windows and macOS for me. Perhaps you can file a bug on bugzilla.mozilla.org

This is the default collection that is on but can be opted out of: https://www.mozilla.org/en-US/privacy/firefox/#health-report
