My off-facebook activity was empty. That's encouraging, because it looks like my countermeasures have been working:

- Fingerprinting resistance in Firefox (privacy.resistFingerprinting = true)

- First-party isolation in Firefox (privacy.firstparty.isolate = true)

- Blocking third-party cookies in Firefox (network.cookie.cookieBehavior = 1)

- Firefox container when I need to login to ad/tracking companies (Facebook, Google)

- uBlock Origin

- Cookie AutoDelete

- PiHole on my home network
