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.
There is no need to click the browser button. Our price history graph is automatically inserted on every Amazon product page. You can contact info@keepa.com if you have any questions.
