/*** [SECTION 8500]: TELEMETRY
Arkenfox does not consider Firefox telemetry to be a privacy or security concern - comments below.
But since most arkenfox users prefer it disabled, we'll do that rather than cause overrides.
Opt-out
- Telemetry is essential: a browser engine is a _very_ large complex beast costing billions to maintain
- Opt-in telemetry _does not_ work and results in data that is unrepresentative and may be misleading
Choice
- Every new profile on first use provides data collection/use policy and the abillty to opt-out
- It can be disabled at any time (Settings>Privacy & Security>Data Collection and Use)
Data
- no PII (Personally Identifiable Information)
- can be viewed in about:telemetry
- uses Prio [1][2][3], Glean [4], Oblivious HTTP [5][6]
