Basic functionality of accepting cookies automatically is fine, but breaks many a websites where I have to go through the troubleshooting process to figure out which of my add ons it could be, why it would be breaking baskets on Amazon, Bulk powders etc and the "add to basket" functionality is beyond me, but it does.

Appears that the last release 3.3.5 blocks some features like the posting of computer on some sites to enter the secret code to access the site. The deactivation of this extension permits to get well functionning site. May be to many change in this last release. Fixed in release 3.3.6. Just install and forget it, it works fine now.

Macht das Internet wieder benutzbar. Bitte auch noch für Firefox für Android verfügbar machen!

After Avast took over the extension, I decided to uninstall it

10/10 but need it for Android Firefox too!!!

Online Cookie-Addon which works for me. Testing since 2 Weeks extensively

The addon is doing what it is made for. No more click orgies. Thanks to Kiko for the good work.

Some sites (e.g. beckhoff.com) are broken when addon is active. Scrollbar is shown for about 1s while site is being loaded, afterwards scrollbar disappears and scrolling is no longer possible. Setting this site on the white list is a work around to use it anyway.

Again thanks to Kiko!!

unfortunately extension died

As of November of 2021, I ("technical data-security" person in public sector) see the legal situation for this addon as follows:

Lets start with a big con about entering legal contracts by surfing in the world wide web:

- Absolutely violates the " informed consent" required by GDPR by sometimes giving consent but hiding what I actually agreed to. Legally, neither the user nor the website now know if anyone is at fault for aggregating and using personal data. I can neither exercise my rights to be informed or correct data that was collected, nor can the website owner use or sell my data in good conscience.

- The developers website acknowledges this schism: "Please educate yourself about cookie related privacy issues and ways to protect yourself and your data. For example, you can block 3rd party cookies, install ad blocking extensions and then block tracking tools, delete browsing data regularly, enable Tracking Protection in your browser etc."
Which is the right way to handle cookie banners. This is the worst way for all parties involved. To reiterate: even the website owners get a poisoned gift by receiving non-legally-valid consent, and the user waives all control over their personal rights without even knowing, how that might hurt him or her whenever this add-on allows some tracking cookies to be stored.

Pros:

+ Visually, seems to work. (Legally, see above. Browser Cookies are not about cookies or computer science, but the actual subject matter is keeping others from knowing what kind of stigmatised interests or ridiculed condition you keep to yourself or a very limited audience. By not caring, you shoot yourself in the foot.)
+ The developer actually reads this and reacts to it.

UPDATE:

Starting in December, this Addon will probably need to register as a "Personal Information Management Systems" (PIMS) in germany, to finally become legal. Let's hope that it won't be an extensive and thereby expensive certification. If @Kiko fails to do that, this app will still work ins legally gray area are finally become illegal in germany and should regionally be blocked to avoid anyone sueing Kiko or the end-users.

The EUs info on that:

This might even of interest for power users or people who actually read EULAs.

I love, love, love this addon!
