Download CatBlock (.zip)

Chrome · Edge · Opera · Brave — Manifest V3

  1. Download & unzip. Save catblock.zip and extract it to a folder you'll keep (deleting the folder removes the extension).
  2. Open your extensions page. Go to chrome://extensions(or edge://extensions).
  3. Enable Developer mode. Toggle it on in the top-right corner.
  4. Load unpacked. Click Load unpacked and select the unzipped folder. CatBlock appears in your toolbar and blocking turns on.
Prefer a one-click install? CatBlock is heading to the Chrome Web Store — until then, loading unpacked is the official way to try it.
