Cookie Auto Decline is a free Firefox addon designed to enhance user privacy by automatically managing cookie consent banners. This tool operates seamlessly in the background, eliminating the need for manual interactions with cookie consent notifications that frequently disrupt browsing experiences. It effectively recognizes and declines various cookie banners from popular scripts, ensuring that users can navigate the web without being bombarded by consent requests.

The addon is compatible with numerous cookie banner frameworks, including Contentpass, consentmanager.net, and cookiebot, among others. It also supports custom cookie banners on major platforms like Google, YouTube, and Facebook, allowing it to function across over one million websites. However, it is important to note that Cookie Auto Decline does not bypass cookie banner paywalls; if decline options are absent, it will default to clicking the accept button.
