Evaluate your content blocker with Ad Block Tester

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.

With Brave Browser defaults, 84% of all hosts are blocked. The list of hosts used in the test is divided into the categories ads, analytics, error trackers, social trackers, mix and OEM. Hosts are owned by companies like Google, Facebook, FastClick, Media.net, Doubleclick.net, or Amazon.

Results are color coded and you may expand a particular selection to reveal all hosts. Red entries refer to connections that are not blocked by the solution. A click displays the hosts, which you may then add to the filter list of the content blocking solution.

It is likely that some solutions are not blocked automatically. Compatibility is one reason why a particular host may not be blocked. Most content blocking solutions may allow some of the hosts in their default states. Users who block scripts, e.g. with an add-on like NoScript, may get a clean score.

Closing Words

Ad Block Tester offers a quick way to test a content blocking solution against a set of popular hosts that are widely used. Connections that are shown as unblocked may be added to the blocker, especially if a site or service is not used so that the likelihood of site compatibility issues is kept to a minimum.

Now You: which score did you achieve and with what kind of setup?

    FWIW: RP showed all the sites it blocked in its ‘denied’ menu, VERY long list.
    Personally, I find it can be more important as to what sites a given site is allowed to draw resources from. It hilites how prevalent google is and how it can track you across the net.

    All the ads attempted to load resources from 3rd party sites — and
    that’s what RQ “governs” — blocking, by defau.t, all requests to unapproved sites.

      Martin’s question was “How good is a content blocker?”. Nobody was saying “my blocker is better than your blocker”. Some of us may wish to not block certain content but still published results.

      Some are using multiple blockers. Unwanted content is obviously high priority for them. Other may not wish to block some content.

      There is also an educational component to people’s responses. Those who scored a low benchmark may decide to change there blocker or add filters.

    DO NOT TRUST ONLY on what your web browser, extensions and other privacy solutions are showing to you! Use an INDEPENDENT open-source program, eg. a packet sniffer (“tcpdump -t -Q out port 53”, Wireshark, etc), to verify the remote connections that your computer opens when you access a page. The web browser and its extensions may be showing wrong results to fool you, when your packet sniffer program, that YOU CAN SEE its source code, study it, modify it and compile it yourself may show hidden things that those do not show.

      @Zelda. On my last computer, a Wireshark update borked my system drive and made it unbootable. I had an up-to-date clone on hand, but I was still pretty miffed at having to unscrew a bunch of tiny screws, swap drives, and screw the bunch of tiny screws back in. Needless to say, I lost my enthusiasm for Wireshark at that point.

      disable adblock plus my hosts file still traps 65%

      Incognito window – 47%

      I guess the 47% would be attributable to hosts file. The 18% gap I suspect is due to DuckDuckGo.

    Hopefully in the future there will be a website like that, when you visit it shows all the ads and tracking your browser/computer is allowing AND has a big green button that will SUPERBLOCK all of it automagically =) This is of course daydreaming, but imagine that defecationstorm it would cause.. Google would block it everywhere, USA would hunt down the guy responsible and have him murdered live on the news by drone-attack, Microsoft would call it a virus and contact every antiviruscompany to flag it as the most dangerous virus webthreat known to mankind. Everyones computers would magically be faster and websites wouldload instantly, no one would ever again be infected by malicious ads..and can you imagine, on your tiny little phonescreen you would actually see CONTENT instead of ads.. oh how glorious that would be! In that same happy world there would be computers running a good, stable and safe windows OS without any microsoft accounts..

    I got 87% on Firefox with uBO, and learnt that it’s not blocking Pinterest, Yandex, or the manufacturer’s sites, (Now fixed for 100%!)…

    And I got 84% on a naked Brave with the built-in standard level of tracker and ad blocking, and the same with Brave shields set at ‘aggressive’. I plan to remedy this by adding uBO or the development build of uMatrix…

    Also, it’s 84% with both Bromite and Brave on my Android mobile…

    This is very revealing — we need more tests like this!

    100% and all green on first launch in my primary browser, Pale Moon, with uBlock Origin and a healthy complement of subscriptions, and with eMatrix set to allow only the current site’s base domain by default. (Additionally, I’ve globally enabled a number of select domains, like CloudFlare.)

    85% on first launch in my main fallback browser, Brave, with uBlock Origin and the same subscriptions as in Pale Moon. (I’m only running “moderate” native shields/adblocking in Brave. It’s a fallback browser, and I’m often already a little frustrated by the time I give up in Pale Moon. I didn’t feel like having to dick around even more to get troublesome sites working in Brave.) 100% and all green after adding the offending URLs to my “My filters” in uBlock Origin.

    84% on first launch in Google Chrome, with uBlock Origin and the same set of subscriptions as in Pale Moon and Brave. 100% and all green after adding the offending URLs to uBlock Origin.

    98% on first launch in Firefox, with uBlock Origin and the same set of subscriptions as in Pale Moon, Brave, and Chrome, and with NoScript set to disallow scripting unless proactively whitelisted by me. (I had to whitelist d3ward.github.io to get the test page to run.) 100% and all green after adding the offending URLs to uBlock Origin.

    I don’t intend to ever use Chromium-based Edge and haven’t done any post-install configuration in it (no uBlock Origin, no nuthin’). The score? 15% and all red on first and final launch!

      By the way, when you use this “Ad Block Tester”, the following annotation will be added to the result.
      Testers should not misinterpret the results.

      As many users reported the host graph.facebook is important to make the service works , so has been removed from the test.
      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.
      Oh, and if you get a bad points when you are sure that your blocking system used works , then probably you are on a browser that manage error connection in different ways so the tool will not detect it .

    The host list d3ward uses to determine which domains to query is available here – raw.githubusercontent.com/d3ward/toolz/master/src/d3host.txt

    If you’re wondering why your ad filters do not block certain domains, add an issue to your favorite adblocker list maintainers (EasyList, AdGuard, uBO) and see if they would consider adding a filter for those domains in the future.

    I use uBO and my lists missed a few domains from Apple, Samsung, Huawei, Yandex and Pinterest.

      @John G. , same here, [https://metrics.mzstatic.com] is shown by the tester as unblocked even when it is (here with uBlock Origin as well as system-wide with a dedicated blacklist operated with DNSCrypt-Proxy). No idea why.

      Another point : even if the tester shows 100% blocked, there might be 1 (or 2?) unblocked urls. The value is obviously rounded off.

Bromite got 94 out of 100 but the domain that was not blocked was showing no plugins supported and so it was not showing any ads, so it was 100 as well.

      God I just love uBlock Origin’s medium/hard mode though its requires patience.

      “didn’t expect to see analyticsdotfacebook not blocked by uBlock Origin.”

      They must have a reason for that but I couldn’t find it after a quick search. Not using Facebook myself I had manually added a rule to block all of facebook.com as third-party which did the job against the analytics subdomain too. I only had to add an exception for instagram.com because it seems to use the facebook.com third-party via CNAME redirection to host legitimate content.

      I am at 94% blocked with Brave now (adblocking set to Aggressive + uBlock Origin, all default lists enabled in both cases).

      In my case, the Facebook domain you mentioned also got through (seriously, neither Brave or uBO stop Facebook Analytics by default, with all default lists?). I subscribed to the following filter lists (hit “Subscribe” at the left side of the screen) and it now gets blocked:

      https://filterlists.com/lists/facebook-zero-hosts-block

      https://filterlists.com/lists/facebook-hosts

      What still gets through is the following:

      https://widgets.pinterest.com
      https://analytics.pinterest.com
      https://extmaps-api.yandex.net
      https://adsdk.yandex.ru

      So basically Pinterest and Yandex, still evaluating how I can also block those.

        To get from 92% to 100%, I had to put the following in “My Filters” in uBO:

        ||widgets.pinterest.com^$xhr
        ||analytics.pinterest.com^$xhr
        ||adsdk.yandex.ru^$xhr
        ||extmaps-api.yandex.net^$xhr
        ||yandexadexchange.net^$xhr

        Made these rules with the help of the logger of uBO.

        Thank you for your suggestions, I am of course aware of the fact that I can use custom entries to the “My lists” section of uBO and I did, yesterday. As per the comment of @Ryan Brown below, the custom entries I added were also added to EasyList yesterday, so I deleted the custom entries, and I am still getting 100% now. So I can confirm the fix introduced by EasyList. :)

        In general, when a specific company gets through my filters, I am trying to look out for special filter lists tackling the problem (because that might cover future domains of that company, too). For example, I don’t want to have anything to do with Facebook or their underlings, so I am now subscribed to Anti-FB lists. I was surprised that the Fanboy’s Anti-Facebook list I was subscribed to before didn’t suffice, same for AdGuard Russian and the RU AdList, how is it possible that those do not cover Yandex?

        Anyway, all good now, I am at 100%.

        I shut off ublock and getting 100% from Brave. So Brave must have updated their lists (or whatever lists Brave uses were updated) because I was only getting 84% yesterday with both Brave and ublock on.

        Yep, Brave uses the EasyList as one of its default lists and the EasyList maintainers added the missing domains yesterday. See the comment of @Ryan Brown below.

        @Iron Heart: I just did the test with Brave an uBO and got 100%! But… there was a message at the top of the screen:

        “As many users reported the host graph.facebook is important to make the service works , so has been removed from the test.”

        So, I’ll also subscribe to those anti-FB lists.

        Just add these to your hosts file:

        0.0.0.0 widgets.pinterest.com
        0.0.0.0 analytics.pinterest.com
        0.0.0.0 extmaps-api.yandex.net

    84% for both Firefox ESR (78.10) and Ungoogled Chromium (89), each with no installed extensions and blocking all third party cookies. Blocking is done only via a hosts file (ex. Steven Black base file: adware+malware only).

    Surprise, surprise!

    Brave with uBlock Origin as extra got 100%
    Vivaldi, with same: 92%
    Microsoft Edge likewise: 100% (huh?)
    Slimjet: 45% (can’t be!)
    Firefox: 92%

    Really surprised here by M$ Edge!

      you should check if you using the same settings in all browsers and your filter list is updated
      I’ve tried vivaldi, firefox dev and chrome/chrome canary
      and I’ve got 100% everywhere
      so I am 100% shure there is something wrong with your setup

      use brave or edge to create backup file and restore settings in other browsers
      for filter lists: purge caches and update them

      Not sure why you’re surprised. Microsoft isn’t an ad company unlike Google.
      Edge has decent built-in tracking protection which in strict mode scores 66% on it’s own. uBlock compliments it well (like any other browser) to bring it up to 100 depending on the filters.

        That are exactly right.
        Microsoft’s ad blocking is decent,
        But instead Microsoft’s “user activities collection” is radical and at the worst level.

      FWIW, here are my numbers:

      Firefox desktop with uBO and a couple of other extensions: 100%
      Vivaldi desktop: 81%
      Vivaldi mobile: 85%
      Brave mobile: 84%

      (I used just the built-in basic privacy settings in the last three browsers.)

      Maybe you got 100% for Edge because you are running Version 90 or above, live in the US, and have Kids Mode enabled.

      Its weird, I have uBlock Origin as well and it showed 100% even in its default state regardless of blocking modes(medium, hard etc), check it again mate as it has new version 1.35.0 available.
      PS – If you’re using uBlock Origin in easy modes then Privacy Badger is a good complementary add-on, but its not necessary in its medium or hard mode.

        Since the website was different, in new website mentioned by developer below, 100 is the score but in uBlock Origin’s medium/hard mode.
