Hot Take Evaluate your content blocker with Ad Block Tester

[CyberTech]

How good is a content blocker? You could say that it is great if undesirable content is blocked while content that you want to access is not, but that is only taking content that you could identify visually into account. Most content blockers reveal information about the level of blocking, e.g. how many items were blocked and how many were not.

Ad Block Tester is a free service on the Internet to evaluate content blocking solutions. It is not designed to be a benchmark, but it reveals the level of blocking against a set of hosts that are very popular.

Just visit the Ad Block Tester website to get started. The test runs for a couple of seconds before the results are displayed. You get a percentage score, e.g. 84% of hosts blocked, and a list of blocked and allowed hosts afterwards.

On mobile I got 84%

I got 84% as well on Edge on mobile. Of as much interest as the percentage was the list of URLs they were testing against. I had heard of the ad, analytics and social ones but not the error tracker urls.

In the last days this tool had of lot of attention , but seems something it's not clear . The test it's not a benchmark tool , and is not a race about who make 100% , it's a reference tool to check if you are blocking any of the host , in this case are used the most important hosts by category and popularity as reference

Firefox 92%
Edge (chromium) 84%

on my testing laptop (both privacy settings set to Strict).

100 % in this test isnt a good thing, just saying.

Ideally everyone get the same result because of fingerprint protection/ uniqueness but sadly the test display the opposite.

100 % in this test isnt a good thing, just saying.

How's that?

Blocking everything may lead to sites not working correctly and so on, thats why my favorite DNS list is OISD (present in NextDNS).

Ps: I got 100 % and I would be totally okay if I got less.

True, but the sites that I added to the denylist are barely/never used in my case. And the ones blocked before (94%) didn't cause any problems either. But you are right in general.

Desktop 85% Firefox+ubo

 

[othmane]

I got 24% on desktop, );

 

[mlnevese]

This test is considering some sites that people may want to keep unblocked such as promotions linked to your search, etc. Also some of those addresses may cause site malfunctions.

Which browser and which content blocker are you using?

 

[Stas]

Brave Browser with built-in ad blocker 98%

Anyone can test Chrome?
At stock settings without any extension or other blocker.

Same would also be interesting for Safari.
