As google promised last year, they have release an update for Chrome that introduces a stronger pop-up blocker that protects against sneaky tactics that lead users to unwanted content through hidden redirects. These abusive experiences that users complained about where often used by shadier sections of the web where the ads or parts of the page included fake site warnings and error messages and “close” button that redirected that page.
Google has also stated that from Feburary 15, Chrome will remove ads that don’t comply with standards overseen by the coalition for better ads.
Chrome 64 also contains 53 various security fixes, and also bring some of Google’s fixes for the Spectre attack that can be used against browsers. Google has also detailed that they will be adding more mitigations in the future.
