By default, Vivaldi blocks advertisements on sites with abusive ad practices, such as ads which are purposefully misleading users and ads using abusive technologies – for example, pop-ups that prevent you from leaving the site.
The abusive ad-blocker feature can be disabled in Settings > Privacy > Content Blocking > Block Ads on Abusive Sites, but we strongly advise you to keep it enabled.
The abusive ad-blocker gives the browser access to a blocklist which is hosted on our end-to-end encrypted servers. It is updated from the server automatically by the browser, and applied to intrusive websites without needing to contact the server each time.
If you’re looking for additional content blocking options, consider adding an Extension to the browser.
