It works perfectly for me. I read the steps and reviews, so I made sure to pin the extension and I am using Amazon from the US as suggested.

doesn't work. here what I see in the console when I click the extension icon: ``` The resource https://images-eu.ssl-images-amazon.com/images/S/apesafeframe/ape/sf/desktop/sf-1.50.17224207.js was preloaded using link preload but not used within a few seconds from the window's load event. Please make sure it has an appropriate `as` value and it is preloaded intentionally. ``` ok. it worked when I switched to amazon.com instead amazon.co.uk. for developers to consider

Extension shows up and loads, but triggers the main amazon page to refresh it's search which causes the extension to close without seconds after populating - great idea but not functional enough to be useful.

This extension shows up in my extension list but not on the browser. I can't see any way to make it work. Disappointing. Would give is 0 stars if I could. Uninstalling.

Load, pin, unload, load....doesn't work at all. It just brings you back to load page. Extremely frustrating. One star only because there's no option for zero.

I have read the other reviews since it wasn't working for me, and they are saying it doesn't work as well. I read one that said to pin it, so that's what I did, and it actually works very well after I did that. It actually brings up all the info including comparing it to Google searches, and it also gives you the keywords used on Amazon to search. I was also able to save all the information. Once you pin it, and get it going, it's an awesome extension.
