Comment (by tom): Ah so this is basically the Visual Viewport I just emailed about, suggesting we don't care about this. The user behavior of zooming and panning can, in theory, give fairly good confidence that User A is *not* User B - because User A zoomed to 150% and User B zoomed to 200%. But to suggest that User B and USer C are the same because they both zoomed to approximately 200% - even if they panned in similar ways - seems waaaaaay too guessy to be a concern. I'll also note that on Desktop, I don't beleive we stop the user from zooming in on a webpage which is essentially the same thing. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/30542#comment:7> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online
