The company announced the security updates this week, the next releases of Chrome will contain three new protection measures.

In Chrome 64, all redirects from third-party iframe will be notified to the user, the iframe, in fact, will display a sidebar of information instead of redirecting. To enable the redirection the user has to interact with that frame.

Another scenario covered by the measures introduced by Google sees users click on a desired destination, which opens in a new tab, while the main window displays an unwanted content. Starting with Chrome 65, this behavior will trigger an infobar and prevent the main tab from redirecting and bypassing Chrome’s pop-up blocker.

“One piece of feedback we regularly hear from users is that a page will unexpectedly navigate to a new page, for seemingly no reason. We’ve found that this redirect often comes from third-party content embedded in the page, and the page author didn’t intend the redirect to happen at all.” states the post on Chromium blog.

“To address this, in Chrome 64 all redirects originating from third-party iframes will show an infobar instead of redirecting, unless the user had been interacting with that frame. This will keep the user on the page they were reading, and prevent those surprising redirects.”

Another scenario covered by Google sees links to third-party sites disguised as play buttons or other website controls.

“Finally, there are several other types of abusive experiences that send users to unintended destinations but are hard to automatically detect. These include links to third-party websites disguised as play buttons or other site controls, or transparent overlays on websites that capture all clicks and open new tabs or windows. ” continues Google.

“Similar to how Google Safe Browsing protects users from malicious content, starting in early January Chrome’s pop-up blocker will prevent sites with these types of abusive experiences from opening new windows or tabs.”

In January, Chrome will update its pop-up blocker to prevent these sites from opening new windows or tabs.

The IT giant is also launching the Abusive Experiences Report alongside other similar reports in the Google Search Console to help site owners and webmasters prepare for this security updates.

The report allows them to check if any of these abusive experiences have been found on their site and improve their user experience.

“Otherwise, abusive experiences left unaddressed for 30 days will trigger the prevention of new windows and tabs.” concluded Google.
