I am using it and it does what it is supposed to, however unfortunately there are a number of sites which break or freeze upon not accepting some cookies or others that won't display all content like embedded social media content (YouTube videos etc.) which is why the button to disable it for certain sites is vital.
However here comes the main concern, this button while there does NOT seem to be doing a tremendous job. I'm not even fully sure if it's permanent or if it's intended to just be temporary and reset. I really need a permanent button for myself and my use case, but the button seems to be overworked, once you use it 3 or 4 times per session it just stops working, it will show disabled but when you go back after closing browser or waiting some minutes it will be re-enabled again, which is - for my particular use case requiring a working permanent button - very bad unfortunately.
So I massively prefer other extensions which are more precise and permanent, like Consent-O-Matic or superagent, but since their filters are manually added, they don't work on all sites, this certainly seems to be working on more sites, but with less precision.
If the disable for this site button was permanent and working flawlessly, I would give it 4 stars, if it was as precise and customizable as above alternatives, while working on more sites than them, I would give it 5 stars.
Have a good 2026.

Funktioniert einwandfrei bei YouTube, Google und allen Newsseiten die ich getestet habe. Gerade weil ich immer alle Cookies automatisch löschen lasse beim schließen des Browsers ein sehr praktisches Tool.

Finally, something that ACTUALLY works, even on Firefox Mobile! Huge thanks to author!!

Doesn't work anymore in facebook and instagram websites

does not work

Das Addon funktioniert soweit sehr gut, allerdings passiert es bei einigen Webseiten, wie zb "metacritic.com", das die Ansicht nach dem Laden ganz nach unten auf die Seite switcht. Das ist nervig und deswegen nicht wirklich brauchbar für mich. Ich hoffe auf ein Fix. Würde es gerne weiter benutzen.

EDIT:
Vielen Dank für die Rückmeldung. Funktioniert jetzt! Bewertung angepasst.

Es funktioniert super. Hoffentlich bleibt das Script up to date, die ganzen anderen Addons die mit der angeblich selben Funktion haben alle so ihre probleme. Props an den Entwickler (Y)

Does the job super well. Makes life a lot easier for me who use the auto delete cookies upon closing feature (I had to decline every single time I used a website).

Thank you for making this. So many of the cookie extensions say they just accept all the cookies or hide the banner, I want them declined and this extension does exactly what I want.

Is there a public source code repository for this extension? I see that it is GPLv3 and looked over the code from the extension itself, but was curious if there's a github/codeberg/etc repo somewhere.

Vielen Dank, dass Sie das gemacht haben. So viele Cookie-Erweiterungen sagen, dass sie einfach alle Cookies akzeptieren oder das Banner ausblenden. Ich möchte, dass sie abgelehnt werden, und diese Erweiterung macht genau das, was ich will.

Gibt es ein öffentliches Quellcode-Repository für diese Erweiterung? Ich sehe, dass es sich um GPLv3 handelt, und habe mir den Code der Erweiterung selbst angesehen, war aber neugierig, ob es irgendwo ein Github/Codeberg/etc Repository gibt.

On paper, better than equivalent extensions. I don't have the skills in the language to know if the code really helps with privacy.

It does work pretty well for the big sites, as far as I can tell.

Would profit from the visibility of an about page in english.
