This is an excellent add on.
I'm all for data privacy use and disclosure but people need to read descriptions before getting their panties in a knot.

Perfect. (To other users: Please read the provided information about the permissions before writing feedback.)

Thank you for the transparency around the recent permission prompts.

I've been concerned recently with this extension failing, but good to see the dev being transparent about why. I could not even tell anyone how long I've had Keepa installed - it's been a long time. Fantastic extension.

A truly useful Firefox Add-on. I'm sorry you're getting reviewed bombed by people who did not bother to read the release notes.

What do you mean you need my authentication information ? I really hope this is a mistake and will get reversed.

Great extension, bringing actual, useful data to Amazon listings!
One additional star for the clear explanation of what data is collected.

Do NOT post BAD reviews if you are not aware of this information (from Keepa support):

"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. This unfortunately triggers the "collecting browsing history" permission.

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".

The extension runs only on Amazon product pages."

Do not blame Keepa for things required by Mozilla.
This kind of "issue" also happens On Google Play.
I'll keep using this addon!

EDIT: False alarm. Good informative response from the developer. Bit of a wrong move from FF.
Searching online and taking a better look at Keepa's privacy policy, it may be not perfect, but I trust it.

OLD REVIEW:
This just became a privacy nightmare. Uninstalled.

Edit: I have adjusted my review under the understanding that this is a change in how firefox discloses data privacy. I would still advise the developers to address some still relevant concerns from Platant's blog post "Data exfiltration in Keepa Price Tracker".

Original: Uninstalling until the recent changes requiring lots of personal data collection is rolled back. There is no need for this info and hasn't been needed for years. Enshitification.

Greed got these guys like it did everyone else. 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.

Love what this does but they keep adding more and more ways to take your data for no reason other than sell it. No thanks.

It does it's job, but why does it need "personally identifying information" ?
I will just uninstall this shit, as if we needed more trackers.
