Seems cool so far, but getting it to show was a bit tricky. Allowing http(s)://keepa.com in the Cookie exceptions did not do the trick - I had to turn off FF's tracking protection for my local Amazon site. Wish that could have been prevented.
Our "Keepa Box", the iframe the add-on injects on the Amazon website, is considered 3rd party on Amazon and therefore data access can be blocked by the tracking protection. Without access to the localstorage the Keepa Box does not work.
They claim that they support amazon.com.br, but they don't! Fake news. The first message you get is: "Keepa can sadly no longer update product data for Amazon.com.br"
Thank you for pointing that out. Sadly we are no longer able to support Amazon Brazil. We have neglected updating the add-on description, which we have now done.
