Do not use Kiwi browser (on Android). It does not allow adblockers to access bing, yahoo, their own websites, and more. Presumably because they get paid

Yandex browser does this too with their own domains.
@coolelectronics I think there was another project called "ungoogled chromium android" that also had extension support, but I think it is discontinued now.
