I only get 82% :( How much do you get?

F, that's the guy who made uBlock... I shouldn't have posted this...
- You could make an edit to your original post explaining the limitations of the method
You are right, I ran the test on Mull + uBlock Origin on a phone running an ad/tracker blocker at OS level, and this tool reported connections that I couldn't find in my logs.
It however helped me identify appmetrica.yandex.ru which was not blocked.

100% because i have javascript disabled.

This test is wrong for sure. It doesn't detect YouTube ads as being blocked despite them never appearing in this browser thanks to ublock origin.

I also highly doubt that any domain from DoubleClick.com would be allowed through ubo.

Yeah, I have a quite aggressive pihole and a lot of the domains it says aren't blocked are 100% blacklisted in pihole (and testing them gives an error message so they are blocked...)
Mull (Firefox) + uBlock + PiHole.
My setup (Firefox+uBlockOrigin) blocks Doubleclick.net. Also, ads.youtube.com is under Social Trackers, maybe it's not the actual ads on youtube, but some tracker? BTW, I have no idea how the internet works, maybe it is wrong...
YouTube ads are just other YouTube videos that you can watch willingly if you know their ID. The mechanism of serving them might therefore not involve the client connecting to any domains other than www.youtube.com, and it probably doesn't or it would be very easy to block them otherwise.

100% on Safari on iOS with AdGuard and PiHol

Same but with adguard home and not pihole

4% is good, right guys?

Better than 3% for sure.
- 33% better, actually.

I opened this in Connect's in app browser and got a whopping 4%. Good reminder to change app settings to use your browser instead of whatever their internal browser is

I get 90% on both mobile and PC.

Firefox on PC with UBlock Origin. Fennec on Android with UBlock Origin.

Both are behind an AdGuard DNS but I think UBlock Origin does most of the heavy lifting here.

If I turn off the "cosmetic filter" it goes up to 92% 🤷

Edit:

Adding the following to "My filters" in UBlock Origin brought it up to 97%

@@*$redirect-rule

100% with cosmetic filter disabled

Thanks for the edit, that fixed mine up to 97% as well.

Seems to be misreporting (Adguard home + ublock origin + FF). With ublock off I get a higher percentage than with it on (93% vs 91%). It's reporting things as not blocked while they are clearly blocked (all requests show blocked in inspector)

this test has been known to have problems on Firefox. 90% Firefox+ublock+nextdns, 99% after using the fix they recommend @@*$redirect-rule in your rules.

96% on /e/OS with the Mull browser with uBlock and Privacy Badger

92% on /e/ on the tor browser with the same extensions?? that's weird

I didn't know people actually used /e/os. not meant to be a dig I'd just never seen it in the wild.
- Yeah I really like it! What do you use?
- Im otherwise just lurking but now you've witnessed two of us on /e/os ;)

89% with firefox for android with ublock origin and decentraleyes.

97% on FF Android with ublock origin. Adguard Home is my network DNS as well.

Testing at 100% w/Firefox + ABP + AdGuard home DNSBL and upstream DNS blocking. Need to get uMatrix back on here.

100% with Cromite's built-in ad blocker + adguard filtering

88% with Mull (default ublock settings)

Before adding "@@$redirect-rule" to uBlock Origin filters:

With uMatrix enabled: 99%, everything except ads-api.twitter.com and ads.youtube.com was blocked.
With uMatrix disabled: 83%, 125/150 blocked.

After adding "@@$redirect-rule" to uBlock Origin filters:

With uMatrix enabled: 100%, 150/150 blocked.
With uMatrix disabled: 85%, 127/150 blocked.

Using Firefox with uBlock Origin, Privacy Badger and some others.

93% with NextDNS and HaGeZi Ultimate.

91% with pihole + ublock on Firefox. Time to add some domains to the blacklist

Yup got the same except adguard instead of pihole. Will add the remaining to a block list also.

Trying a few different browsers I have installed:

Firefox in Strict mode with LocalCDN: 42% (eww)
Brave (stock): 72%
Brave w/ stock uBlock Origin: 78%
- 100% w/ custom filters enabled
Opera w/ uBlock: 75%
Vivaldi (stock): 55%
LibreWolf w/ uBlock and LocalCDN: 70%

100% with iOS Safari, Wipr, and Adguard Home on network level.

100% on Safari with just Wipr.
Wipr is pretty nice.

87% with Firefox on MIUI. I think I have some custom ublock filters? Not sure because my config was copied from my PC.

93% on mobile (Firefox + ublock + pihole) 84% on desktop (Firefox + unlock + pihole)

I got 100%. Using Mull on android (Firefox fork) with Ublock.

69% on my network alone. More once I turn ublock origin on :)

Seems to still not work correctly. I remember a little while back that this testsite had issues with how uBlock Origin handled some blocking. Seems like the issue has not completely been fixed. Strange that the github issues all seem to have been closed.

96%

Using mull+ublock for android on GrapheneOS with DoT on Adguard Home.

Interesting, I can't block ads. youtube and ads.twitter but they are added into my blocking lists. Sus.

These results are not at all what I expected. Safari + several blockers seems to be best, followed by Brave of all browsers. Firefox and FF focus got the worst rating! I really thought Focus would do a better job. Then again, all cookies get deleted so at least that part won’t matter much.

Firefox focus gave me a 93% while fennec gave me a 91%. I run ControlD as a DoH provider that is suposed to block ads, trackers, malware, and big social (X, spybook, instabully, etc). I am also running ublock origin in fennec.

Edit: damn, adding privacy badger took it from 91% to 96%.

Edit 2: ouch

Fennec + privacy badger 39%
Fennec + privacy badger + ublock 87%
Fennec + privacy badger + ublock + Controld DNS 96%

4% on duck duck go browser. 87% on fennec.

For me it's trackers from Twitter and YouTube that are responsible for the remaining 3 %.
- Yep, same here. Got 96 and Twitter and YouTube ads are the culprits

99%
This is with Firefox in strict privacy mode with uBlock, Privacy Possum, Local CDN and CanvasBlocker. I don't think any other of my addons matter for this.

Edit: I also use Mullvad VPN which might block some stuff on the way too.

I've been using UBlock for years and was surprised that out of the box, AdGuard had a much better score!

Firefox (Fennec) on Android. uBlock Origin with every single block list enabled.

84% on Fennec mobile with AdAway, uBlock Origin, Privacy Possum, Ad Nauseum and DecentralEyes. A lot of sites seem to be wrongly reported though, ad.doubleclick.net for example.

5% on stock chrome for Android. Guess this week is the week I switch to firefox mobile (73% with stock uBlock Origin)

91%, Firefox with ublock and Privacy Badger on a network with pfBlockerNg.

93% with NextDNS on an iPhone.

Got 92% on Firefox iOS in strict mode, with pfblocker. Tried safari but the test won’t even start.

96% but it's not accurate. Verified on my DNS logs that the two it claimed weren't blocked, actually resolved to 0.0.0.0 correctly, so I'm actually at 100%

90% with my normal setup, but I highly doubt it's correct because:

literally everything in uMatrix except first-party scripts is blocked
it goes up to 93% when I turn off uBO, yet the page loads way more slowly which makes no sense

The site does say uBO on Firefox has unknown issues, so I'll attribute it to that.

100% using Orion on macOS, no extensions.

It's a damn shame that browser only exists on the mac. When it comes to Linux, I'm going for it.
- I really like Kagi. If their browser is half as good as their search engine is its going to be fantastic.

89% according to the tool, but should be 100%. The tool itself says it can't detect it in some cases. I manually checked the 16 domains it flagged aa unfiltered and neither of them worked.

Wow I only get 62%. Using Vanadium on GrapheneOS over a network with DNS blocking.

DNS adblock will still not come anywhere close to a browser adblocking extension. They want to add content filters to Vanadium eventually though. But if you care about adblocking, Firefox is really the only way to go, and also doesn't contribute to unhealthy Google monopoly.

100% with AdBlock and LocalCDN on LibreWolf.

91% on Chrome mobile behind PiHole. Fairly good for a minimum effort whole network solution.

Got 100% on ios using Orion with Ublock-origin

91% on Firefox for Android with I lock Origin and pfblockerng on my router.

Just trying on mobile first, 57% in the in-app browser and 55% in Vivaldi vs 87% in Firefox. Even if the percentage is wrong it's interesting for comparing between browsers. Looking forward to trying on desktop (I haven't seen an ad on desktop in years) and seeing if I can improve adblocking on my phone later today

90% on Vanadium (which has no ad blocker) + Mullvad VPN. Good enough.

That's insane. I only got 62% on Vanadium + Proton VPN + nextdns.
- Try adding some blocklists, maybe the Hagezi ones. I remember NextDNS being quite good at that test.
I got 73% in Vanadium + mullvad VPN... I also have adguard-dns set up.

91% 🤝

I have quite a few browsers installed, all with adblock.

surprisingly, vivaldi did the best with 85%

81% using Firefox on Android with uBlock on a pi-holed network

What blocklist do you have? I have the default one and am getting 79% with your same setup
- Aside from the built-in lists I have AdGuard Mobile, EasyList, EasyPrivacy, Malicious URLs and Peter Lowe's list

93% with Firefox and privacy badger on Windscribe VPN adblocking enabled. 55% with Windscribe disabled.

93% on my iPad with an ahaDNS profile installed. The only thing that makes it through are Apple’s stuff. All things considered, I’m fine with that.

74% with ublock origin for Firefox

100% with Brave in aggressive mode, and a Pi-Hole behind it.

96% using Android Firefox Beta with ublock, nextdns, and a VPN.

Nextdns AND a VPN? 🤔
- I pretty much always use a VPN these days because I hate Comcast and don't like them seeing my traffic. I like nextDNS because it gives me centralized management and filtering of DNS for all my devices, it's definitely worth the $20 a year. I forgot to mention I also have the extensions CanvasBlocker, WebRTC Blocker, and LocalCDN but I think it is likely just ublock origin (and nextDNS filtering) that got my score to 96%.

87% with NoScript, Privacy Badger, uBlock

93% with Firefox and Ghostery behind Windscribe VPN. I've got a few other addons disabled like Decentraleyes and Ublock, but a combination of those with Ghostery didn't do any higher. Pretty sure I disabled them because Ghostery did everything they did. The stuff let in are to make websites like Youtube and Google usable. It's a tradeoff.

Was getting 71% on Librewolf with only uBlock Origin. Enabled every blocklist in the extension and am now getting 100%. Thanks for sharing!

53% with stock Firefox Focus on Samsung galaxy

96% with Brave Browser (android) and DNS66 (custom block list)

90 % with UBO+Pihole

99% in Firefox with uBlock Origin, Privacy Badger, Decentraleyes and AdGuard Home.

I got 93% on mobile with the same setup.
Although I'm not sure if decentraleyes is working

Interestingly, I get a better result with only nextdns profile with hagi pro on iOS 87%, compared to nextdns + iCloud private relay 37%. What gives? Nextdns still handles my requests with private relay enabled, I can see it in the logs of nextdns.

I also use the Firefox focus safari extension.

Score is also slightly less with nextdns and proton vpn at 81%.

I rather liked to iCloud private relay nextdns combo, should i change.

Orion gave me 100%, but that browser isn’t as polished compared to safari on iOS.

private relay is likely using apple DNS to resolve blocked domains.
- More tech savy people analysed the dns jumps, and I think the understanding was it goes through both IPR’s and Nextdns’s DNS. If so, I still imagined this block test to show a result where everything had been filtered by nextdns at some point in the route.

100% with Firefox for Android and Blokada. 100% with Firefox 117 beta for Windows (advanced tracking protection + uBlock Origin).

93% blocked running on my exentionless chrome on my phone. Damn I love pihole.

100% on Samsung Browser with AdGuard extension, and AdGuard Home as my DNS Adblocker.

96% on Brave at home (pfBlocker).

81% on Firefox with uBlock Origin at home (pfBlocker).

100% with Adblocker Ultimate.

90% with uBlock Origin.

I usually use Adblocker Ultimate.
To check it, I disabled all the other extensions.

83 with Firefox, uBlock, Privacy Badger and DuckDuckGo Privacy Essentials

97% with Vivaldi and 87% with Mull +uBlock Origin... That's surprising.

I got 100% in Vivaldi on mobile by going into the settings and selecting "Block trackers and ads" and then selecting every single one of their ad blocking sources (the list was from all different countries). That got me 100% with no addtional add ons.

87 % on mobile, 97 % on the desktop

This much

Here is an alternative Piped link(s): https://piped.video/fJTuldpMwCg?t=37
Piped is a privacy-respecting open-source alternative frontend to YouTube.
I'm open-source, check me out at GitHub.

I added advice-ads.s3.amazonaws.com and ads.youtube.com to my ublock filter and those two still aren't getting blocked, anybody know how fix? the other two sites I added block fine.

82% on Firefox mobile + ublock origin + adguard home inside Tailscale.

75% on Mull with Ublock origin... I need an alternative but I like Firefox.

91% on mobile Firefox with ublock origin and adguard dns blocker on my home network.

I have the exact same setup, and I got 80. 🤷‍♂️

With the inbuild Vivaldi adblocker

Enabled only two filterlists

Apart other 2 for blocking cookie advices.

91% On Firefox with Privacy Badger, Nord VPN, Ghostery, a DNS filter as well.

89% without @@*$redirect-rule in My Filters, 96% with it added. Just using uBlock Origin with all filters on regular Fennec for Android (Firefox stable fork), and dns.adguard-dns.com private DNS sprinkled on top. Getting rid of that redirect rule though since I'm guessing it'll just cause breakage for me.

79% with firefox with ublock, and pihole dns with stock blocklist

100% ublock origin Firefox + NextDNS + privacy bager

100% with just uBlock Origin

95% - Firefox + Privacy Badger + Ublock Origin + VPN.

The sites that are "not blocked" are sites I've specifically allowed because I use them.

88% brave android, then adjusted my nextdns deny list , now 100% 😁😁 peeps on adguard, move to nextdns. adguard owned by Russians so I'm told.
