hello, what happened to the functionality that allowed us to accept the strict necessary for the proper functioning of the sites? because it's good to hide the cookie popup but some sites gray the page until we have accepted the cookies and the addon does not allow to remove this gray.

Good but needs a better method to not break sites. Currently twitter.com and tweakers.net are broken and the failure mode of landing on an unusable site leaving you with no clues is just awful.

The update pop ups are annoying.
EDIT: Yeah, it pop ups once. Still annoying.

nützliche Erweiterung !

Update: the author decided to start sending custom headers to websites as explained at https://www.i-dont-care-about-cookies.eu/cookie-installing-permission-header/

This could be exploited as a fingerprinting vector, so make sure to disable those notifications in the addon's preferences if you're concerned about your privacy.

Pale Moon 28.4.1 x64

As soon as the addon was updated to 2.9.9, the browser behaved like a crawl.
Slow. Sluggish. Choppy.
One core full load, so 25% CPU usage all the time.

As soon as I downgraded back to 2.9.8 - issue gone immediately.

And I use this source, because Pale Moon does not support WebExtensions:

It breaks websites.
The idea is good, however it seems like it plainly hides the cookie warnings instead of accepting them.
This results in websites that are unusable. You click elements that don't react, you try to scroll but it won't work, etc. You refresh maybe thinking maybe something didn't load correctly, but nothing you do will fix the website, but disabling this addon and accepting the cookie notification.
It caused great frustration initially when I had no idea why can't use a website.
Edit:
@Kiko
Turns out I didn't even have the latest version because for some reason the minimum version is now 57. So in browser updates won't work on v56 that I use.
Edit2:
Now I reported them.

A utiliser conjointement avec l'option de suppression automatiques des cookies a la fermeture de FF, sinon, trop dangereux de tout accepter.

Work's fine

Je viens de réactiver I don't care about cookies, mais j'ai un doute : dans le cas où il nous est demandé d'accepter les cookies, est-ce que le plug-in les accepte tous ? Est-ce qu'il ne peut pas au contraire nous aider à tous les refuser?
Par exemple, quand je vais sur Recode-Decode, sans I don't care about cookies, j'ai le choix entre "Accepter" ou "En savoir plus" sur les moyens de refuser (ce choix est déjà bien planqué). Est-ce que "I don't care about cookies" accepte tout à ma place? Ou bien agit-il comme Qookiefix qui rétablit le bouton "Refuser" (mais seulement sur les bannières Quantacast). J'aimerais bien que ça aille vers ça, un peu comme le faisais Self Destroying Cookie (mais Mozilla l'a condamné pour des problèmes de sécurité…)

It used to be excellent and extremely easy to operate, but since last update it has become very bothersome reporting a cookie warning with filling several fields on a page and, incredibly, using latest Google captcha, which is the most stupid captcha ever seen, because it uses very small pictures with ridiculous microscopic details that we often can't see properly and go round and round verifying pictures. Crazy, really crazy. And, on top of all this, it asks for our e-mail!

There has been a much improved change since my comment, 3 days ago.
Before, when I tried to send a report it asked to complete the form fields. No more now.
The crazy Google captcha was now replaced, another great improvement.
It is very good when a developer listens to people, as in this case. I replaced the given 3 stars with the well deserved 5.

Supprime la plupart des bannières d'autorisation de cookies.

Au temps pour moi, le problème vient de Quantcast depuis l'application du RGPD.
J'ai installé une appli qui me redonne le contrôle de certains cookies sur ces sites pourris : https://addons.mozilla.org/fr/firefox/addon/qookiefix/
Je garde "I don't carre..." car il fait bien son boulot sur les autres sites.
Merci
