Chrome 64 is now in beta and it has several new features over version 63. In addition to a stronger pop-up blocker and support for HDR video playback when Windows 10 is in HDR mode, Chrome 64 features sitewide audio muting to block sound when navigating to other pages within a site. 9to5Google reports: An improved pop-up blocker in Chrome 64 prevents sites with abusive experiences -- like disguising links as play buttons and site controls, or transparent overlays -- from opening new tabs or windows. Meanwhile, as announced in November, other security measures in Chrome will prevent malicious auto-redirects. Beginning in version 64, the browser will counter surprise redirects from third-party content embedded into pages. The browser now blocks third-party iframes unless a user has directly interacted with it. When a redirect attempt occurs, users will remain on their current page with an infobar popping up to detail the block. This version also adds a new sitewide audio muting setting. It will be accessible from the permissions dropdown by tapping the info icon or green lock in the URL bar. This version also brings support for HDR video playback when Windows 10 is in HDR mode. It requires the Windows 10 Fall Creator Update, HDR-compatible graphics card, and display. Meanwhile, on Windows, Google is currently prototyping support for an operating system's native notification center. Other features include a new "Split view" feature available on Chrome OS. Developers will also be able to take advantage of the Resize Observer API to build responsive sites with "finger control to observe changes to sizes of elements on a page."
