Update from February 21, 2026 Add-on v.2.1.3:

Advantages:
+ The best thing is that the removal process is very cleverly designed: cookies/pop-ups are removed, the scroll bar is repaired, and then any blurred overlays (blur elements) are accurately removed.
+ The developer takes extremely good care of updates and responds to feedback quickly and reliably – perfect!

Disadvantages:
- Error v.2.1.3: the chat function is no longer available on ebay.de – entered responses are not posted, even if PopUpOFF is set to “Turn OFF”!!! The chat function only works again after deactivation!!! (-2 stars)
- When using additional add-ons such as “I (still) don't care about cookies,” many shops/social websites still take much longer than usual to load (Amazon, eBay, YouTube, Reddit, etc.). But it's not quite as bad as it used to be. (-0.5 stars)
- The add-on is quite good at detecting and removing stubborn banners/cookies, but simpler ones are NOT blocked (usually those with an “X” to close them!). However, it often recognizes the latest methods for overlays/banners. (-0.5 stars)

Conclusion: This add-on is very powerful and a great tool with a first-class developer (I've been using it since the beginning and long before it was as famous as it is today). For even better detection, I strongly recommend:

1. Fix the bug that prevents ebay.de support chat from working with the add-on!
2. Add the detection rate of “Cookie Banner Blocker” (author: otsmr) to your code. After that, captchas still need to be added to the whitelist (otsmr does not have this). This would probably make the add-on even better than “I (still) don't care about cookies” and “superagent.”

Aktualisierung vom 21.02.2026 Add-On v.2.1.3:

Vorteile:
+ Das Beste ist, dass die Entfernung sehr schlau durchdacht ist: Cookie/Popup wird entfernt, die Scrollbar repariert und danach ggf. ein verschwommenes Overlay (blur-Element) zielsicher entfernt.
+ Der Entwickler kümmert sich extrem gut um Updates und reagiert auf Feedbacks schnell und zuverlässig, perfekt!

Nachteile:
- Fehler v.2.1.3: auf ebay.de ist die Chat-Funktion nicht mehr möglich - eingegebene Antworten werden nicht gepostet, auch wenn PopUpOFF auf "Turn OFF" steht!!! Nur nach Deaktiveren funktioniert die Chat-Funktion wieder!!! (-2 Sterne)
- Bei zusätzlichem Verwenden von Addons wie "I (still) don't care about cookies" dauert das Laden vieler Shop/Social-Websites immer noch sehr viel länger als üblich (amazon, ebay, youtube, reddit, etc). Aber es ist nicht mehr ganz so schlimm wie früher. (-0,5 Sterne)
- Das Addon ist ganz gut in der Entdeckung und Entfernung von hartnäckigen Bannern/Cookies, einfachere werden hingegen NICHT blockiert (meist die mit "X"- zum Schließen!). Es erkennt aber oft die neusten Methoden für Overlays/Banner. (-0,5 Sterne)

Fazit: Dieses Addon sehr mächtig und ein tolles Werkzeug mit einem erstklassigen Entwickler (ich benutzte es seit Beginn und schon lange bevor es so berühmt war wie heute). Für eine noch bessere Erkennung empfehle ich dringend:

1. Behebe den Fehler, dass Einghaben im Support-Chat von ebay.de mit dem Addon nicht mehr funktionieren!
2. Füge deinem Code die Erkennungsrate von "Cookie-Banner-Blocker" (Autor: otsmr) hinzu. Danach müssen noch Captchas auf die Whitelist gesetzt werden (otsmr hat dies nicht). Dies würde das Addon wahrscheinlich dann sogar noch besser machen als "I (still) don't care about cookies" und "superagent".

works fine, but slows down a lot of websites A LOT even really basic stuff like Wikipedia. not sure what is goin wrong with it

I found that this add-on interfered with several websites that I used regularly. One was the Washington Post site. Also NYTimes and IMDB. When I turned off PopUpOFF, things on these sites went back to normal.

I can't say that this app is the only contributor to my problems, as I have other add-on blockers installed as well. Also the problems I had with websites evolved over time, so there may have been contributing causes from website changes. But when I stopped this add-on, problems disappeared.

The developer responded that there was "confusion" about how the addon works. When I go to the Washington Post website with PopUpOff installed, the entire page fails to show up. Then I halt the addon, and the Post page goes back to normal. That not confusion about how the addon works.

I appreciate those who develop addons. I use a bunch of them. Some just don't work, at least not on my browser. My review noted the possibility of other causes of interference. I gave a balanced review of my experience. It's not confusion.

completely breaks twitch.tv for the most part and hasn't been fixed in the past year

For some reason, this add on seems to "break" ebay's purchased items "tracker". Turn it on and it takes forever to open the pane where you can see your shipping status and then it takes an equally long time to close it after you're done. It's not my hardware as I'm running a very new and very high spec'd MSI gaming laptop. It's lightning fast on every web site and program I visit/use. Removed the app and ebay site was back to normal behavior. Tried several other pop up blockers and none of them break ebay. Currently running "pop up blocker (strict)" and no negative effects on any web site. It's possible firefox or ebay changed something recently, as I used this app for about a week without this problem. Kinda scared me that I may have picked up a keylogger or virus somewhere, but MaCafee and Malwarebytes came back with a clean report after a couple scans. So, unfortunately, I can not recommend this add on while it has this limitation, at least not if you use ebay much.
