Much depends on what's in the tile. For example an embedded 1 pixel
transparent gif, commonly known as a "web bug", and loaded from a
third party web repository such as one of the many misleading aliases
, is one of the favorites. Another is crafting
the URL used by the displayed advertising page to contain metadata
about the browsing client. Unless the tiles are vetted by, hosted by,
and have their content reviewed and manually sanitized by someone both
paranoid and content over at Mozilla, it's safe to assume there is
tracking information embedded in the tiles. The tracking information
has become ubiquitous in far too much web content, especially in paid
I'm afraid it's not reasonable to assume that just because Mozilla is
providing the hooks to publish web ads that those web ads do not,
themselves, collect and use personal user data, especially the client
IP and browsing history.
The Ads title looks like:
<div class="newtab-site" draggable="true"
<a class="newtab-link" title="CITIZENFOUR
<input class="newtab-control newtab-control-pin" type="button"
title="Pin this site at its current position"></input>
<input class="newtab-control newtab-control-block"
title="Remove this site"></input>
So Mozilla provides offline thumbnail of the page and URL, nothing else.
The ads work completely offline.
