Chrome 66 mutes launched videos automatically

Chrome 66 comes on Windows, Mac, Linux, iOS, Chrome OS and Android, with the feature of mute videos that start automatically.

Google announces the deployment in the coming days and months of Chrome 66 in stable version for Android, Chrome OS, Linux, macOS and Windows.

As promised last month, this new version of the browser Google blocks, by default, the sound on videos with automatic reading.

Exception based on the MEI

This feature was initially expected on Chrome 64, which included an option to completely disable site-by-site audio. The latter itself was expected for Chrome 63.

On Chrome desktop, Google uses the Media Engagement Index (MEI) to determine if the user has already viewed a video with sound on a site. On mobile, automatic playback with sound will be allowed if the user has added the site to his home screen.

Chrome has this index measuring the interaction of Internet users with the media (MEI). It assesses the propensity to consume media for each site visited. It is possible to check his MEI for each site by accessing the internal page chrome: // media-engagement .

The exception to the default mute of auto-initiated videos is based on whether you’ve ever watched auto-play videos on a particular site (measured by the MEI) or saved this site on the screen. welcome your mobile device.

Sandbox to fight Specter and Meltdown

In addition, Google uses Chrome 66 to perform a site isolation test, which is supposed to prevent pages from different isolated websites in their own sandboxes from preventing data theft attempts. from other sites by malicious sites.

Site isolation is an additional layer of security that ensures that Web pages are always placed in different processes and in sandboxes limiting what these processes can do.

It can also stop speculative attack techniques on side channels, made possible by CPU design flaws such as Spectrum and Meltdown.

Although Microsoft seems to be working on its own version of Site Isolation, a study comparing the security of major browsers released last year showed that Chrome’s site isolation was more complete and less likely to be bypassed by attacks.

Other features

Google has also added an “Export Passwords” option that will be exported to a CSV file.

Chrome 66 also fixes for 62 security bugs.

In addition, Chrome 66 removes approval for digital certificates issued by Symantec’s previous public key infrastructure by June 2016. In Chrome 70, which is expected to be stable in October, all Symantec certificates will stop working and will display a warning of certificate in the browser.

For features for developers, Chrome 66 includes the ImageBitmap rendering context for the canvas tag. Instead of first creating an img tag, then rendering its contents in a canvas, which results in storing multiple copies of the image in memory, this new context streamlines the display of ImageBitmap objects by avoiding duplication. memory. Google notes that a game using the WebGL JavaScript API could for example use it to load new textures on the fly as the game progresses.

Uncompromising domination

Google’s Chrome browser dominates the web browser market, claiming 57.7% of Internet users use mobile and desktop computers in March, leaving Apple’s Safari browser second with 14.8% of the market , according to StatCounter data. Chrome is actively used by more than one billion people.

This means that the changes made by default in Chrome should have a significant impact on the operation of the websites.
