|So in recent builds of Firefox new tabs have collected "suggested" site tiles. Now being marketed to and having my meta-data sold to the highest bidder is why I moved back to Firefox from Chrome about a year ago, so the appearance of "marketing" in Firefox's UI is quite concerning.|
Of course you probably want to know how to turn those suggested site tiles off right? Well see that little gear icon in the top right hand corner:
Unselect the "Include suggested sites" and you're good.
