Well, not nice Rated 1 out of 5 stars

maybe it's doing what it's suppose to, but it's doing much more: it adds this "&tag=deff-21&tag=deff-21&tag=deff-21" to any amazon url, so the author gets a commission by the amazon affiliates program. Other plugins are doing similar things BUT they declare it rightfront. This is a no-go!

Auf Deutsch:Das Plugin fügt auch jedem Amazon-Url die Zeichenfolge: "&tag=deff-21&tag=deff-21&tag=deff-21" hinzu, wodurch der Autor bei allen Einkäufen Provision mitschneidet. Das machen andere Plugins auch, aber die geben dies auch gleich öffentlich zu, nicht jedoch hier, daher: Nein danke!!!

Not nice either

Hi, thank you very much for your review.
You are absolutely right, that I added my amazon affiliate tag.
But as it should be I declared it under the link privacy (="Datenschutzerklärung"): https://addons.mozilla.org/de/firefox/addon/shipped-and-sold-by-amazon/privacy/)

Sorry for any inconvenience!

Very cool Rated 4 out of 5 stars

I would feel better if it was explained technically how this works but, hey, it works!

Hi darthgarlic

You just just need to add the toolbar button to your toolbar and click the button when you are at an amazon website.

Here is a nice instruction how to do that:

I hope I could help. Best regards.
