Broken on Firefox/Fennec for Android as of 01/17/26 According to another review it's due to switch to cloudflair. NextDNS logs implicate a Cloudflair DNS component as a "bypass method" attempting to circumvent private DNS rules. This was never a problem. Let's hope they fix.

it was good when it worked, but now it only says

"Firefox Can’t Open This Page

To protect your security, keepa.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window."

but opening Keepa's frame in a new window doesn't load, so it's useless on Firefox now!

edit: The Camelizer - Price Tracker still works on FIrefox, but it requires you manually click it to see the price, compared to how Keepa used to automatically show it on the main product page (back when it worked.)

Inside the extension lives `keepa.js`. A notable file and it preforms its duties well. I enjoy using this extension but I have to make personal modifications.

1. Disable Bug Reporting (Telemetry)
reportBug:function(a,b,f){}

2. Disable Background Scraping (The "Botnet" Feature)
108108==b.timeout?(b.stockData&&(c.stockData=b.stockData)):(b.domainId&&(aa=b.domainId));};

3. Disable Invasive Stock Checking (Session Hijacking)
initStock:function(){}

4. Stop Sending Browsing Data
case "sendData":f({});break;

Since keepa is eula I cant share my derivative of keepa. They have no option to disable any one of these invasive features. If you really want to you have to edit the source code by hand like I have done. I will change the review to 5 stars if they choose to make these changes a toggle and change the license to GPL 2.

Beworben mit "von Amazon startbar" ich seh da nix.
Adon gestartet auch da ist es wenig intuitiv.
schlechte dokumentation
gleich wieder deinstalliert

Cette extension valait 5 étoiles, jusqu’à l'utilisation du stupide antibot de chez cloudflare qui tourne en rond et n'affiche jamais la suite.
Si vous voulez bloquer les humains, cet antibot est parfait.

This Keepa Firefox-addon WAS a FIVE star, but now it has become totally unusable due to the cloudfare anti-bot. No way to stop the "I'm a human" loop . This is so sad because it WAS so GOOD. I've been using it for years !

It was so great, when it worked on firefox.
Now, it won't work because, now it's using clouflare which always blocks me and now I'm asked to remove my adblocker!!??
NO!
This is a stupid request - and why do you need cloudflare?
What a disappointment!

I have been using this extension for a while and I like that it works right out of the box without a bunch of configuring. I also like that it has filters like price drop alerts and such, although I haven't gotten around to using them.
-1 star for: "This add-on is not actively monitored for security by Mozilla. Make sure you trust it before installing"
I'm not sure how you're supposed to be able o quickly research and monitor the security of an extension.

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.

paid shit
