Extension Metadata

About this extension
While the extension is available as a backup, I recommend using uBlock Origin instead. It not only blocks YouTube ads effectively but also enhances privacy and offers broader features.
Get uBlock Origin

This lightweight tool changes YouTube web links to a special website called youtube-nocookie. That way, you can watch videos without ads or cookies.

Just click the extension icon or the Floating NO COOKIE Button to tweak YouTube links to enhance privacy. It will automatically send you to youtube-nocookie, which is a privacy-enhanced mode of the YouTube embedded player, giving you a smooth, interruption-free experience. This add-on aims to offer a better, faster, and ad-free space for watching YouTube videos. Simply by adding a parameter to the link, the extension takes you to youtube-nocookie, so you can enjoy the content you want without any disruptions.

Pin the extension to the browser's toolbar for quicker access!

-Supports SponsorBlock.

Important Note:
YouTube made youtube-nocookie to follow the GDPR (General Data Protection Regulation), which is a European Union law about privacy. Because of this, the extension, which simply redirects for you, is unlikely to stop working soon. It also boosts your privacy, even if you didn't request it!
Please be aware that modifying URLs and redirection involve interactions with external sites. Ensure you comply with YouTube's terms of service and policies.

P.S. I originally made this add-on for myself, but I think it's important to share things that can benefit others. As a result, the extension doesn't gather or share any data to prioritize privacy. I believe strongly in maintaining privacy, and I'm against anyone collecting unnecessary data.
Developer comments
In rare cases, after you use the extension, you may see a ‘Video unavailable’ message. The script normally prevents this, but it can’t do anything if the video’s creator has disabled YouTube embedding.

Since Google’s policies are trash, I’ll never pay their US$ 5 developer fee to upload the add‑on to the Chrome Web Store. The add‑on is and will remain exclusive to Firefox and its forks.
