edit. I’m using Firefox now, as I noticed that vertical tabs were already available in an earlier update. Hagezi’s Ultimate, TIF Full and a few custom ones in uBlock.
I use two browsers, Brave for some general internet use and Tor for anything more sensitive.
I deliberately don’t try to block the maximum on Brave, because I need to allow some things for sites that I regularly use.
Testing the site you linked, the Tor result was much higher than Brave, as expected. I don’t think the exact percentage is useful, as the site itself does say there are bugs.
But it’s interesting to see how different combinations get different results.
Everything works fine in my opinion. I haven’t noticed any problems for a long time. And I only came across this page yesterday, so I didn’t block anything based on that.
The flaw in the current case is that the tool is unable to understand that uBO redirects many blocked network requests to a local resource, in order to lower likelihood of website breakage and to prevent detection to defuse anti-content blockers.
76% on Brave + ProtonVPN. Only 21% with Vanadium + ProtonVPN. The Vanadium one is a bit surprising but it did give me a warning that it has compatibility issues with some browsers so that could be why.
As someone has already pointed out, adblocking tests are inherently not reliable.
See this issue on uBlock Origin. In that issue there are also links to useful resources, like this.
Adblockers often redirect network requests to local resources instead of blocking them, because otherwise websites may break or an anti-adblock could easily detect the adblocker.
So the website isn’t supposed to be able to detect what gets blocked.
Though this makes me wonder why on Brave that test reports ~90%: shouldn’t it report a low percentage like on Firefox with uBlock Origin?
I got: Brave 99%, Firefox 98% and MLullvad 70% (tbf for mullvad i haven’t touched any settings it’s mostly out of the box, and i have 4 addons (cookies and user-agent which is disable)
uBlock has a much more logical and proven approach than Brave on a number of issues. Both block the sites concerned, but with uBlock this blocking is transparent because the client interprets it as “functional” and not blocked. This is very useful when you want to hide a potential block.
Don’t use adblock test sites ; they’re useless and unreliable.
For Brave i use Brave shield and some of the settings recommended by PG and i have nextDNS. For Firefox i use the recommended settings by PG (not all of them), ublock origin with Hagezi Pro filters and nextDNS (keep in mind that if you have a low score on Firefox there is a bug with the website and there is a way to fix that in the FAQ i think, and after you’ve use that fix, remove it or it will mess up with the filters of Ublock origin) For Mullvad just the out of box settings + nextDNS
I wonder why your brave + proton is so low. My brave without proton enabled was 98% and I have the settings recommendation from PG. If I enable proton it doesn’t change
