Big news for anyone who hates cookie notices:

We've open sourced Cookiecrumbler, a system that automatically detects these notices across the website and suggests fixes for them.

Cookie notices are those irritating pop-ups that ask you to accept cookies when you visit a website.

In addition to being annoying, these pop-ups can also harm your privacy. Researchers have learned that these cookie consent systems sometimes track users even if they reject cookies:

Brave blocks cookie notices by default. However, this feature relies on filter lists that can break some sites if the lists' rules are either too broad or incompatible with specific sites.

We needed a better solution. This is why we developed Cookiecrumbler.

Cookiecrumbler uses open-source LLM models to automatically detect cookie banners across the Web in multiple languages.

This frees up time for human reviewers to then design blocks for these pop-ups.

The result is better blocking and fewer broken sites.

We're now publishing results of Cookiecrumbler crawls across popular websites on GitHub: github.com/brave-experime…

This will allow the ad blocking community to review these findings so we can further improve cookie notice blocking for everyone.

Blocking cookie notices is part of our broader commitment to a privacy-first and user-first Web

Our browser also blocks third-party ads and cookies along with other cross-site trackers.
