Seems that this isn&#x27;t what I thought: an ad-blocker integrated into Firefox directly.<p>They are apparently no longer going to be advertising in &quot;Tiles&quot;, whatever that is. A quick search makes it seem like an optional interface for the new tab page, before any navigation has occurred.<p>I don&#x27;t use Firefox so can&#x27;t really comment about Tiles, but I would be kinda annoyed seeing ads on the new tab page in Chrome.
