Gosto muito dessa extensão, uso bastante no chrome, mas aqui no firefox ela não suporta o layout da amazon.com.br, fica sendo sobreposta por outros elementos na página o que torna ela inutilizável. Espero que consertem.

Does not support Amazon Australia website

When I try to open Options from the Keepa's Add-on page in Firefox, I get the following error:
Firefox Can’t Open This Page

Bei Amazon sehe ich sofort, ob ich besser mit dem Kauf warten soll. Dank der variablen Zeitachse kann ich den nächsten Tiefstpreis abschätzen oder den Preis-Alarm einstellen. Mir gefällts!

I love this add on alot! I used to stab myself in the eye but this addon made all that nonsense stop and IT also helped me considerably with my stuttering problem!
Thanks keepa amazon.com price checker!
