What would be great is if there was a setting so that it only made a product comparison when I was actually adding a product to my shopping list or to my wish list. It does alert to items available at Amazon when I am at other web sites HOWEVER there is a constant barrage of comparisons and they aren't always a better price or even a similar item. Sometimes it made a price comparison when I was on a website that didn't seem to be selling anything. So it doesn't work right. I also get some error messages. So I gave up on it. Mostly I wanted to get the 'add to wishlist' button back but it wasn't worth the aggravation.
