I looked into these settings but I can only find 4 checkboxes. Which of the four checkboxes would this telemetry fall under? Is this a study, the result of crash report logging, or is it "data about your interactions with Firefox [..] (such as number of open tabs and windows; number of webpages visited; number and type of installed Firefox Add-ons; and session length) and Firefox features offered by Mozilla or our partners (such as interaction with Firefox search features and search partner referrals)"
I know Firefox collects some technical tracking, but there is no up to date overview of what tracking is actually done. Is there a list of parameters tracked like Microsoft published [1] after the outcry about their terrible tracking? The privacy policy is vague and the documentation for developers [2] contains phrases such as "opaque prio-specific payload. Like { a: <base64 string>, b: <base64 string> }" which isn't exactly useful.
