    A FOSS chrome extension that attempts to remove the annoyance of cookie pop ups and banners. There are some extensions out there that auto-accept cookies, but I didn't find one that auto rejected cookies without either chaining some extensions together or setting up custom rules in tools like uBlock origin.

By using Extension.js, adding the package to your npm scripts is all it…

    Hello everyone! This is a browser extension that attempts to enhance Hacker News user experience, while your data is kept secure, and private (never leaves the browser).

    Hi HN, I am working on a small side project called FavBox. It is a local-first browser extension that extends your existing bookmarks. It builds on your browser’s native bookmarks instead of replacing them or changing your default workflow. Key features: syncs with your browser profile, no third-party data sharing, no ads. no tracking. Clean, minimalist UI with tags support.
