Nothing about how Keepa handles data changed in this update.
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".
