Not sponsored, I just genuinely like the product. Adguard doesn’t require manifests because it works outside the browser.
But trivial to circumvent. Just change the origin url from (for example) ‘ads.google.com’ to ‘google.com’ and you no longer can block ads based on DNS blocking.
While it is now not a hugh thread it will eventually happen when they manage to eradicate adblockers in the browser.
