Wonderful Features :)

It's good to have amazon assistant make more easy while searching the product.

Great addon!!

Very helpful

Nice addon, really handy sometimes

Alright, so... This extension works *almost* great when it works. I start all my reviews with a 5 star rating, rounded down, as it seems there is more often "useless" 5 star reviews more often than "useless" 1 star reviews.
This one has lost 1 1/2 stars instantly, due to many issues with saying I am signed out when I *just* signed in, and seeming to fail to detect my amazon account at least half the time.
The second issue I have, is, when I am signed in, it seems *unable* to display my current shipments and orders on the extension, without loading the amazon website, despite their being an extension for it, losing it 1 star. It gained 1/2 of this star back though, bringing it to a total of 3/5, due to order notifications working, and at least I can know when it arrived to go check my door/mailbox.
I *can* reccomend this extension for heavy users of amazon who just need to know if their package should have arrived, but for casual users or heavy users who check their shipments obsessively, you would be better off just leaving an amazon tab open, unless notifications are a major draw for you.
I will likely update this review as the extension changes.

Other extensions I have likely to impact results:
Ublock Origin + Custom block lists: Might be responsible for the login issue, but disabling and restarting browser seems to have had no effect

Good extenstion to get updates, recommendations etc

stopped working after the latest firefox update

The assistant helps me discover new products available at Amazon. Love it!

Stopped working on firefox update

doesn't work as of lately

Firefox76.0に更新されたらまともに動かなくなった。

2020/05/08追記
また動くようになったので評価を修正。

Stopped working when I updated Firefox to v76.0 a few days ago. Had worked flawlessly in Firefox v75.0.

ottimo

Doesn't seem to work any more. It just says 'Cookies are disabled in your browser' which they are not. I have tried on 2 different PCs and it is the same.

Very useful plugin

WOWWW

Amazon Assistant for Firefox is a great tool, and user experience can be enhanced if you provide an option to the user to maximize the screen. The window is small and the user has to click multiple times to view the entire selection of products.

Just woww!

Very good product.

A really helpful app that's easy to use. It saves me a lot of time clicking around comparing items, prices, deals, related products and suggestions.
The only thing I don't like so far is the the amount of screen space this app uses, which is about 25% of my screen. It covers important info on right side of the Amazon.com website. Making the app look more transparent while in use would earn it a 5-star rating.

Works well for everything Amazon!
