- While the extremely worrying "new" permissions may just be an artifact of Mozilla new categorizing for disclosure, the module still seems to go behind the user's back using his browser to execute unrelated requests for it.
Whether this is abnormal in relation to Mozilla or Amazon guidelines, and GDPR, and the requirements for the developers, I cannot properly evaluate, but I'm still concerned about.
I would encourage the developers and users to eg read Wladimir Palant's blog post titled "Data exfiltration in Keepa Price Tracker". - New requirements:
What's happening: The new "data collection" categories you're seeing aren't Keepa suddenly requesting more access — they're part of a new disclosure format Mozilla now requires from all Firefox extensions (rolled out since late 2025). Developers must now explicitly declare data categories that, in many cases, the extension was already handling — this is just making it visible.
Why these categories match Keepa's actual function:
* Browsing activity — Keepa needs to detect when you're on an Amazon product page to show price history.
* Website content — it reads the page (product name, ASIN) to build its price charts.
* Personal data — likely covers optional contact info (e.g., email) if you set up price alerts.
* Technical/interaction data — marked as optional, probably standard analytics (errors, browser version). You can decline this without losing functionality. 개발자 답글

Mozilla now requires every add-on to declare data categories from a fixed list, and Firefox displays them on update.
What Keepa does: on an Amazon product page it sends that product's ASIN to keepa.com to draw the price chart. It is not logged and not retained. Nothing is stored unless you choose to track a product. The "personally identifying information" line refers to your Keepa session token - a login credential for your own account, not your name or email. We think that's the wrong label and have asked Mozilla to change it to "authentication information".

6시간 전에 게시됨An der Art und Weise, wie Keepa mit Daten umgeht, hat sich durch dieses Update nichts geändert.
Mozilla verlangt jetzt von jedem Add-on, Datenkategorien aus einer vorgegebenen Liste anzugeben, und Firefox zeigt diese bei einem Update an.
Was Keepa macht: Auf einer Amazon-Produktseite sendet es die ASIN dieses Produkts an keepa.com, um den Preisverlaufsgraphen zu laden. Diese Angabe wird weder protokolliert noch gespeichert. Es wird nichts gespeichert, es sei denn, Sie entscheiden sich dafür, ein Produkt zu verfolgen. Zeile für „personenbezogene Daten“ bezieht sich auf Ihren Keepa-Sitzungs-Token – ein Anmeldedatum für Ihr eigenes Konto, nicht auf Ihren Namen oder Ihre E-Mail-Adresse. Wir halten das für die falsche Bezeichnung und haben Mozilla gebeten, dies in „Authentifizierungsinformationen“ zu ändern.
Die Erweiterung läuft ausschließlich auf Amazon-Produktseiten.개발자 답글

There would be far more users if you made it affordable for everyone. But you decide to track more user information and cut way down the free version. No thanks. Look elsewhere, there are some really good competitors. And to think I have to now warn all the people I told to install it.
