A very good add-on, get rid of the shameless cookies-popup! Please make this add-on to work on the android platform! I'm using firefox mobile but this app won't working in my browser. Thank you dev.

Why is this still a recommended addon?

Sold to the known spyware company avast, sadly not recommended any more

for deviantart, it seems to break the website as it doesn't register mouse clicks UNLESS you whitelist the site. there may be more sites out there like this but personally, this is the only one i experienced.

bought by avast. Use the open-source version "I still don't care about cookies"

Spyware as all avast products

This extension has been bought by Avast.
Here is a new version of the extension: https://addons.mozilla.org/en-US/firefox/addon/istilldontcareaboutcookies/

The extension works most of the time. Even though it need a few seconds until the cookie banner disapears. The reason why I can only give two stars: It claims it would reject cookies automatically. But in the seconds the banner is visible, you can see that it allows most of the cookies automatically. And you can't prevent it. I don't like that and wouldn't choose that manually.
