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

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.

Does not work. Installed on latest firefox and win 11, No chart shows up on amazon.com or amazon.ca product pages.

Does not support Amazon Australia website

It's good, but somehow it manages to circumvent the Container separation which is scary; and if you enable it on Private Windows, your Keepa user (as with Containers) is still logged in even on the Private Window, which is even MORE scary.

This means that Keepa (and associates) can track you even when using Containers and Private browsing.

I disabled it for Private browsing, but I'm thinking of disabling it also on normal browsing.

No .com.au support

doesn't support Amazon Australia

E' inaccettabile che si debbano obbligatoriamente accettare tutti i cookies, senza poter scegliere soltanto i necessari

Used to work, now there is just a big white space on Amazon pages.

Used to use it while buying @amazon.co.uk but unfortunately it`s useless @amazon.pl

Won't recognise my login details.

Doesn't work. Clicking "options" refuses to open inside Firefox settings and redirects to some external site. Useless.

Not installed on Firefox for Android

Doesn't work for Amazon Australia despite requiring that permission

The page says no account needed, but it seems they make the extension unusable without one. I just installed the add-on, and I clicked the Keepa button while looking at a product on Amazon. Instead of getting any price history, I get a complaint that I'm not logged in. Not very helpful at all.
