>When starting up Tor, aren't you confronted with a message about not maximizing the window?

I've never seen that message before, but that would explain why it always opens up 'windowed'.

I'm pretty sure that because Tor Browser ships w/ `privacy.resistFingerprinting.letterboxing` set to `true` by default since 9.0 [1] (Oct. 22 2019 [2]), users can resize the windows now without affecting their fingerprint.
