Vivaldi, the startup founded in 2016 by Opera cofounder and former CEO Jon von Tetzchner, joined the fight against abusive ads today with the launch of Vivaldo 2.6, the newest release of its eponymous web browser for Windows, Linux, and macOS.

This edition’s spotlight improvement is a feature that blocks ads determined to have “abusive technologies,” those that are intentionally designed to be misleading or obtrusive.

Abusive ad blocking arrives alongside a filter for saved passwords, as well as a spruced-up profile switcher and “find in page” utility and a new notification icon for unread tabs in the Window Panel.

“The way that we’ve implemented [ad-blocking] functionality is an interesting step in the direction of relying less on third-party services.”

Ads that qualify as “abusive” in Vivaldi’s book include fake messages (e.g., elements that resemble chat apps), unexpected click areas (transparent backgrounds), misleading behavior (close buttons and navigation links that lead to an ad), browser history manipulation, social engineering (phishing and deceptive sites), auto-redirects, mouse pointers, and malware or unwanted software.

Vivaldi 2.6’s built-in ad-blocker prevents them from displaying, granting browser clients access to an enabled-by-default blocklist (the same Google uses for Chrome) that can be switched off in the Privacy section of the Settings menu.
