Also, my understanding of Tiles was that it would be showcases for

know (and therefore the government by subpoena could know) that ID

this is a history leak to a degree - can we find a way to mitigate it?
But I do think we need to keep things in proportion here.
So here's another piece of information that belongs in the privacy
notice: Is the data being collected here only for the tiles that
Mozilla sends and _not_ for the tiles that come from a user's history,
or are they for every tile on the newtab page, including the ones from
a user's history?
Based on knowledge I only have for an hour or so:
Enhanced Tiles are only shown for sites that by frecency show up in your
new tab page.
There's a collection of Enhanced Tiles locally in firefox, and if it
spots a site it knows about, it'll show you the enhanced tile instead of
the website screenshot.
So, enhanced tiles data reflects the popularity of that site in your
history.
