use Quantum 63.0.3 (64 bit)
not work japan(amazon.co.jp)

What would be great is if there was a setting so that it only made a product comparison when I was actually adding a product to my shopping list or to my wish list. It does alert to items available at Amazon when I am at other web sites HOWEVER there is a constant barrage of comparisons and they aren't always a better price or even a similar item. Sometimes it made a price comparison when I was on a website that didn't seem to be selling anything. So it doesn't work right. I also get some error messages. So I gave up on it. Mostly I wanted to get the 'add to wishlist' button back but it wasn't worth the aggravation.

Doesn't work at all, just error messages and intrusive 'suggestions'. Have given up on it now after numerous attempts and am uninstalling it. I just want the 'add to wishlist' button back. If they were trying to stop people from adding external items to the wishlist and force them to use amazon more they've failed, they've achieved making me not want to use an amazon wishlist at all. UK.

It doesn't work. I'm not able to use it at all.

Semble ne pas fonctionner sur le site France.

Awful, bloated replacement to their previous Amazon button. It also hangs when you change the region from US to UK.

Non funziona per Amazon.it

Installé il allait sur .com aux usa... entrée dans settings pour changer .fr ---> programme freeze. désinstallé. à lire d'autres commentaires, encore une idée à moitié cuite, heep....

En anglais !
et impossible de l'avoir (comme je l'ai déjà eu) en français...

Unable to change region without the add on hanging and giving:
Error code: ext103 4d8f5e03-310c-43da-aa7b-f88bce451f40
Close and reset.

Doesn't work. Either says there's a problem and asks to close and restart, or, on the rare occasion it does actually load, it hangs whenever I try to do anything within the plug-in. This has happened in both Firefox and Chrome, and on multiple systems.

On top of that, it's a bloated plug-in that tries to do way too much. It was nice when it just worked to add off-site things to my wishlist, but now it's slow and cumbersome to use.

This terrible extension slows down browsing dramatically, rarely works, and is constantly failing. All I want is to add items to my Amazon wishlist, and in classic Amazon fashion, they couch the functionality I want in a clunky, poorly designed piece of garbage. Just bring back the wishlist extension and stop pretending to be a customer-facing software company.

Doesn't work at all (UK). Spins for a while then says it couldn't load (with ext103 error in tiny text at the bottom), as per many other reports here. And all because the “add to wishlist” button has been “retired”. Hey ho, the onward march of progress.

Despite using Traditional Chinese in my Firefox, and setting the country setting in Amazon Assistant as UK, as well as physically living in UK, Amazon Assistant still amazingly decided to display in Simplified Chinese.

No funciona en Amazon.es

No funciona para amazon.es
It does not work for amazon.es
FF 63.0 (64-bit)

It doesn't work. Cannot get a connection at all and keeps wanting to restart. So, doesn't not work on Firefox Quantum.

Like so many here, I LOVED the "Add to Amazon" button that I used to use. This POS doesn't work AT ALL.
I WANT THE BUTTON BACK!
The bookmarks for orders, account, etc work just fine. But the ONLY part I want, the "Add to Wishlist" just shows up a blank gray box, as does "Home".

I keep getting a "I'm having trouble loading" message, nothing seems to fix the problem.

Absolutely useless. I used to use the wishlist button which worked perfectly. This doesn't work at all. I simply get the message "Sorry I'm having trouble loading" each time I use it. What a shame!

una vera porcheria... quando funziona è lentissimo... ma di solito rilascia un messaggio di errore...
