Gale, it's not a QB feature. I assume you're using Google Chrome or IE. It doesn't show up for me in Firefox, but it does in Chrome. It's for that reason I use Firefox as my browser & DuckDuckGo as my search engine -- to cut down on all the tracking and data collection that goes on so many places online these days. It was creeping me out when my iPhone would send me an instant coupon as I walked past certain stores, or my browser would hyperlink to merchants in the middle of an otherwise decent little article.
