Nano Defender

An anti-adblock defuser for Nano Adblocker and uBlock Origin

Installation instructions

Nano Defender can only protect either Nano Adblocker or uBlock Origin, and will prioritize Nano Adblocker.

We are looking for maintainers for Firefox and Safari ports.


Step 1. Install Nano Defender.

That is it if you are using Nano Adblocker! If you are using uBlock Origin, then you have a few more steps to follow...


Step 2. Enable Adblock Warning Removal List.

Step 3. Install Nano Defender Integration filter list.

Step 4. Go to uBlock Origin dashboard, select "Settings" tab, check "I am an advanced user", click the gears that shows up, replace "unset" after "userResourcesLocation" by "https://jspenguin.com/NanoAdblocker/AssetsMirror/NanoResources.txt" (without quotes).

Note: If you have another User Resources in use, then you would need to either switch to Nano Adblocker or manually merge resources. It takes an eternity to get any resources into uAssets, I have tried.

Note: If you are using uBlock Origin, then you must have a functional Internet connection when you touch anything in the dashboard.

Step 5. Install Nano filters.

Step 6. Install Nano filters - Whitelist.

Note: My filter lists are now hosted on my own server after criticism from Raymond Hill. Although the old links will still work if you prefer them.
