Those webpages used to "test" blockers are frowned upon, see: https://x.com/gorhill/status/1583581072197312512

There are many reasons that sort of online tools are not able to reliably test a content blocker:

- Many content blockers are designed to fool pages to think no content blocker is installed

- Content blockers filter according to real, actual cases, not synthetic cases used in their tests

I just tested with Firefox and uBlock Origin in the stricter "medium mode" and got a score of 1%. So yeah, I don't think these test pages are that great.

Would you be supportive of an "adblock test page" that literally just reports if the adblocker is working correctly, rather than how good it is? Like maybe an EICAR-like rule that is added to EasyList that matches an element on that page?

There is. If you are using uBO Lite, enable the "uBlock test filters" list, wait a bit and click on the home page button at the right. It will lead to https://ublockorigin.github.io/uBOL-home/tests/test-filters....

I'm using AdGuard with Mac Safari and I get 96%. Perhaps this is a configuration issue. But if that site doesn't test for false positives, which it doesn't seem to, I'd say the result is pretty meaningless.

It says on the page that ublock origin breaks the results. Now that might be the full firefox version but in my test with Firefox the result was 1 blocked on the page but 125 on the extensions own notification.

I got 7% with uBO Lite on iOS. The test doesn't seem that reliable.

I’m getting different results for it with every reload, is that normal? Ranges form 56-96%

Wipr 2 full 100%

Must depend on your block lists, I get a 98% using AdGuard on iOS. I'm using easy list, easy privacy, fanboy annoyances and social filters, and hagezi's light dns filter. I'm a big fan of ublock but I don't see much issue with AdGuard for now.

Wipr 2 scores 100%
