Nano Adblocker Core

Just another adblocker

Nano Adblocker is based on uBlock Origin.

Please open an issue if there is something you want us to know.

This repository contains the legacy code of Nano Adblocker, the new code can be found in the Nano Core 2 repository.

Chrome Web Store approves new builds within seconds but Microsoft Store takes weeks for a new version to be published, so the Edge version will be somewhat behind and that is out of my control.

Warning: Do not install from unofficial sources! Any websites that are not linked below are considered unofficial.

Get it for Chrome

Get it for Edge (Beta)

Maintainers wanted for other browsers (open an issue and let me know)

Get Nano Defender, the perfect companion extension for Nano Adblocker
