It's rubbish! Can't get it to do anything

Simply will not work on my Win-10 Pro with Firefox 66.0.3 (64 bit). Worthless!

Ho provato a installarla e disinstallarla più volte su diversi pc, ma da sempre lo stesso problema: non appena si seleziona l'Italia l'estensione va il loop infinito e non funziona. Direi che così è inutile.

Silly me - I assumed that since I use Firefox on both my Mac desktop and my Windows 10 laptop, the Amazon assistant would migrate, with the browser, from one platform to the other. Boy, was I wrong. Every time I restart Firefox on the Windows 10 laptop, the Amazon assistant is - go figure - missing. Not the best customer relations experience!

Per L'Italia non funziona.

There is no usage of this addon for me. Its home page is www.amazon.com. Well I am not an American and my homepage is somewhere else. When I open Amazon page using this one, my list of orders is 0.

As far as I can tell, this add-on does nothing useful whatsoever. Having not observed any of its 'benefits' during the past year, in which I've made only 6 or so purchases from Amazon, I have to assume this is a fairly useless app for the less-than-avid consumer, such as I.
It claims to show comparisons to "thousands of sites" but, this is Amazon's claim, not an independent arbiter's.

dos not work

So ridiculously annoying it's useless. There are no settings to shut off the annoying banners that pop up on virtually EVERY stupid site. Assumes I want to see what Amazon has to offer REGARDLESS of what I am looking at. Stupid app needs to have settings so I can say when to show me stuff and when not too. It does what it wants so It's going away.

One of the most useless and irritating apps I was foolish enough to install. It resisted all attempts to remove it until I discovered I0Bit Advanced system care.

Leider muss man einen Stern vergeben - eigentlich wären es NULL Sterne. Dieses Addon ist völlig unbrauchbar, wenn man Bestellungen auf anderen Plattformen als amazon.com aufgibt - die werden einfach nicht angezeigt. Sehr seltsam für ein angeblich globales Unternehmen ...

Nach Sprachumstellung... nur gehler läuft seit Tagen nicht mehr

No funciona para España, se queda colgado. Does not work for Spain, it gets stuck.

Solo funciona para la página USA, al intentar cambiar a Amazon España se queda colgado. Ya me ha pasado varias veces con Firefox Quantum 64, 64 bits, asi que voy a eliminar la extension.

I wanted this add-on. I clicked the button for this add-on. Then it switched me the Amazon France ... because me and my computer are in France. BUT WHY DOES IT THINK I UNDERSTAND FRENCH JUST BECAUSE MY COMPUTER AND ME ARE IN FRANCE AT THE MOMENT? Why swtich languages? We were getting along very well in English; why not keep to what was working ... English?
Over 18 years in spending lots of money on Amazon ... ALL in English.
So now I do not have this add-on. No big loss for me.

Ne marche que sur .com
Work only on .com ...

Cette extension ne semble pas fonctionnelle dès que l'on passe sur Amazon France. Cela la rend tout bonnement inutile dans le cas d'un utilisateur français.

Doesn't work unless you want to be on the American site. Will not let me change to UK, just say the is an error, which is obvious. I've now installed and reinstalled six times, still doesn't work!
