Doesn't block Yandex and Yandex.Direct ads. This is painful, since I often use Yandex services and just don't want to see about ten of ads on weather forecast page. Other than that - it's great ad blocker.
Fast, efficient etc. - all what you need from this class of addons. Weren't it for these Yandex ads - I would continue using this addon. As things stand now - I've got nothing but return to Adguard.
