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 for ad.doubleclick.net, 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 advertising content. 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.
