Rating & Review BreakdownA 4.3 built from 70% five-star and 15% one-star ratings is a very different product from a steady 4.3 — and Amazon shows you only the average. This add-on puts the breakdown on the product page, next to the stars, where you are already looking.
Free, no account, no ads. Nothing leaves your browser.
Both of these are rated 4.3. The difference only appears when you look at the shape of the rating — which is the whole reason the panel exists.
The rating and the percentages are Amazon’s own, read from the product page itself, and they cover all of the product’s ratings. The lines about verified purchases and posting dates describe only the reviews Amazon lists on that page, and the panel says so. Nothing is estimated or inferred.
Firefox used to answer this question for you. Its built-in Review Checker was retired in June 2025, and Fakespot — the service behind it — shut down on 1 July 2025. What went away with them was not only the scoring, but the simple act of showing you the shape of a rating.
This add-on does the small, checkable part of that job.
Rating & Review Breakdown for Amazon does not collect or transmit any data.
It reads the rating information already present on the page you are viewing and displays it. All processing happens locally in your browser. Nothing is sent to us or to any third party.
One setting is kept in local storage: whether you leave the panel expanded or collapsed. That is a single true/false value. No record of which pages you visited, no product identifiers, no ratings, no review data.
Access to Amazon domains is requested solely to read the rating histogram, and the
storage permission solely to remember that one setting.
amazon.com, .co.uk, .ca, .de, .fr, .es, .it and .com.au. The numbers are read as numbers rather than as English words, so the panel works the same on a German or Spanish storefront as on the US one.
The code ships unminified — three small files, readable in a couple of minutes.
