In general this addon is very very good, it already saved me a lot of money. But currently it´s not working, I can´t see any prices in the Keepa box.
Does anybody know how to solve this problem? Or is an update of the addon planned?
As soon as it´s working again, I will change my rating to 5 stars.

Keepa is an excellent tracker for Amazon pricing. I haven't used other Amazon price trackers besides Honey, and I think Keepa blows honey out of the water.

It seamlessly integrates with the Amazon product page without being annoying, and allows you to setup alerts on product prices and lightning deals regardless of seller. The in-page graph makes it exceptionally easy to see if now is a good time to buy, and also makes it easier to see if its worth reviewing used options.

Additionally, Keepa requires a narrow scope of permissions which I highly value, only pulling information on amazon owned domains. This is far better than apps like Honey that request all of your browsing data.

I love this app and highly recommend it to anyone who uses Amazon.

I've been using keepa.com for years and really like it, but the add-on doesn't appear to work, at least out of the box. Reading some comments it seems I might need to lower some security feature for it to function but none of the things I tried worked.
If the add-on needs extra steps to actually work, that should be mentioned on its front page and/or app settings!
Also, I'd expect at least clicking the add-on icon while I'm on a product page would go to Keepa's pricing history on that product at least, but it just loads my tracking list.
So, right now, the add-on has no use at all for me, unfortunately.

It works great, but only on the american amazon website. Being Australian, it doesn't seem to work with the .au variant of the website, which is a big deal breaker for me.

No funciona en la última versión de firefox para Android

Estensione molto utile, ti consente non solo di monitorare l'andamento dei prezzi ma anche di ricevere alert personalizzabili sui prodotti, avere un confronto diretto tra ebay e amazon e infografiche su prodotto e venditore

Muy útil aunque a nivel estético tiene margen de mejora.

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.

It's working great on Windows. But why is it not working with Firefox for Android (daylight) anymore?
