Test Ad Block

Compatibility Table

The test relies on JavaScript, it can encounter problems due to browser limitations and varying solution approaches.
Below you'll find browser-adblock solutions that have been validated and tested to work effectively

You will not see any ads and no trackers will be activated A configuration with multiple solutions at the same time can lead to false positives.

While some browser+adblock solutions may not be supported by this test it's important to note that this does not imply they are not effective or reliable

Adblock Solution

Browser-Platform

NextDNS (DNS)

Can be used in combo with ublock-origin or adguard adblocker. Test doesn't work properly if blocking page feature of NextDNS is enabled

FAQ

How does it work?

You will not see any ads and no trackers will be activated

Blocked

If the connection to a host/script fails or a box is removed means the latter has been blocked by your ad-blocker

Not Blocked

Connection to a host did not fail or box is not removed, means that your ad-blocker did not block it or doesn't work

After tests are completed , you get a liquid color ball with points.
Points are calculated based on your tests for each category and type
The color fits your points range
Here a preview of 3 scenarios :

Cmon , use an adblock or smth

Ok, but you can do better

Great, you're ready to surf

The tests consist of 3 types

Cosmetic Filter : Check if you are hiding/removing the empy boxes of ads, cookie policy etc.
Script Loading : Check if you are blocking a possible ad script loading or trackers
Host : Check if you block domains that provide trackers, analytics or ads

I'm sure my ad-block solution is configured correctly, but the test does not work.

It would appear that your current configuration is not compatible with the type of checks carried out by this tool.
However, please note that this does not mean that there is a lack of protection provided by the solution you have configured, such as an ad blocking extension, a VPN or a DNS.
The limitations of JavaScript or the absence of certain features may prevent the test from being able to accurately determine the number of connections that are blocked.
You will still receive an estimate of the percentage of connections that have been blocked/detected by this tool

How I can have 100%

A green score indicates a satisfactory level of protection.
There is no need to aim for a perfect score.
However, if you are interested in achieving full 100% protection, you can use my d3Host List, which covers most of the tests on the site (excluding cosmetic filters and script loading). This should help to improve your score.

My ad-blocking solutions

I use DNSFilter as main DNS resolver
Great alternative for home consumer users NextDNS Plus these combo on each platform :

Windows : Brave + ublock-Origin
MacOS : Brave + ublock-Origin
Android : Kiwi Browser + ublock-Origin
iOS : Brave with built-in adblock enabled OR Safari + Adguard Extension

uBlock Origin Adguard for iOS

Others test tools for your adblock

I created this project to quickly test my small list of most common hosts.
I wanted to build something with a great design and user experience that was pretty straightforward for any type of user.
There are other great tools that I use and would like to recommend

The test may not work as expected with some browser/blocker combinations.
To ensure a smooth experience, please check the compatibility list before testing.

I ask that you please refrain from reporting them directly to the browser or adblock solution provider.
Instead, I encourage you to report problems directly to the Toolz project issues
