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.

Very helpful tool. I use the free tier and it covers the basics. Anyone worried about the recent permissions update: TLDR; nothing new as far as I can see.

Under Manifest V2 (v4.19), permissions and host access were lumped together under one simple umbrella.

Under Manifest V3 (v5.63), web browsers separate functional browser permissions (like saving your settings) from target host permissions (the actual websites the code can touch).

Because the code structure changed to the modern template, Firefox handles this as a permission change and forces a manual review, even though Keepa is still only targeting Amazon and Keepa domains to overlay its pricing graphs.

Super comme extension

Very good, thanks !

Absolutely PHENOMENAL service to offer for free. It's super helpful to get price alerts and more importantly price HISTORY for almost every item I can find on Amazon! Thank you!!

всё летает, багов не заметил

Me gusta esta aplicación

Muy buena y útil, siempre la uso :)

Really good. Nowadays a lot of things say they are on sale but it can be very misleading. I have no complaints about this extension.
