Description
This project is open source and is available on Github.
https://github.com/aldi/coronablock
CoronaBLOCK gives you control over your Facebook feed by automatically hiding posts and comments that contain COVID-19 related keywords.
It runs entirely on your machine (no servers, no analytics), and works by scanning the page as you scroll.
Key Features:
Real-time filtering: Watches the feed and hides matching items as they appear.
Toggle on/off: Enable or disable from the extension popup.
Counter + badge: See how many items were hidden (popup + extension badge).
Privacy-first: Keyword matching happens locally; nothing is sent anywhere.
