I am aware only of Yandex & Kiwi as Chromium browsers that support extensions that allow you to install an adblocker. So perhaps Brave is trying to integrate itself there somehow by having it built in.
Anybody know a better breakdown than this for mobile browser market share? https://gs.statcounter.com/browser-market-share/mobile/world... It says Chromium is 61% and Yandex is 0.1% but it would be nice to see if Brave was included or not.
