This isn't really an addon. it's a shortcut..

Please, add amazon.pl. Doesn't even need to have language support itself (just like .fr/.it/.es) but would greatly help with browsing there.

Masterpiece

Been using this for years. Love it! Very useful! Well designed.

Intrusive plugin with a mediocre UI. Doesn't even work on most amazon products. This plugin is only here to grab your data.
Avoid it.

Will support for amazon.nl (Dutch) be added to this extension in the future?

Wonderful add-on to see what the previous prices really were. I'd even love to have a link next to the Amazon price that scrolls down to the keepa chart.

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.
