It's nice to have a slightly less biased Amazon. Though it's still an evil website that manipulates search results, this makes things a little better, at least!

**Okay, if you guys find that it's "not working", then check U-Block Origin. Not sure when the change happened to cause it, but now my sponsored products are blocked natively by it! I set an exception, because I prefer the highlight behavior provided by this extension. (FWIW, I use "advanced user mode", so I'm not sure whether it happens by default in "basic" mode.)

The domain that results in the block is amazon-adsystem.com. (I think they're inevitably loaded from a2z.com, but blocking the other seems to prevent a2z.com from being called.) Pretty interesting how they're not returned in the original result set. (Not that their original results don't already have a bunch of manipulation going on.)

Seems to only work on the search results page. Worth remembering that the "Products related to this item" in item pages now contains some (or all?) sponsored links.

Update: It seems that it does not highlight or block products listed under "Highly Rated" and "New Arrivals" which are sponsored, too. By simply hovering over those products, I can see the "picassoredirect" link. Hopefully, it's not too much work and the developer sees that and can update the extension.

Honestly, it's worth 5 stars but I would love to see a blue frame like in the screenshots provided in the addon page or the highlight color in light red. The light grey simply doesn't stand out much. Nonetheless, great and helpful extension.

Works great, except on smile.amazon.com
