This essentially means that Google is phasing out the method that web developers use to trigger Chrome extension installations from their own sites. But while Google can't do much about that convention on Android, it is putting its foot down on Chrome.
Initially, any Chrome extension first published from Tuesday (12 June) onwards will have auto-install blocked.
Part of what makes Chrome so popular is the availability of extensions through the Chrome Web Store - allowing users to customize their Chrome experience to suit their own needs. "When installed through the Chrome Web Store, extensions are significantly less likely to be uninstalled or cause user complaints, compared to extensions installed through inline installation".More news: ‘Dumbo’ First Trailer: Tim Burton Brings Disney’s Lovable Elephant to Dazzling Life
"We continue to receive large volumes of complaints from users about unwanted extensions causing their Chrome experience to change unexpectedly", explains James Wagner, Google's extensions platform product manager. Google found that these inline installations actually took away necessary information that a user could rely on to predict the usefulness of the extension, as well as instructions on its use. That is, extensions that are installed from websites other than the Chrome Web Store and are, therefore, not vetted by reviews, descriptions, and the like.
This will force users to visit the Chrome Web Store directly to install Chrome extensions.

As a result, Google has made a decision to retire inline installations on all platforms.
⥤ Starting September 12, 2018, inline installation will be disabled for existing extensions, and users will be automatically redirected to the Chrome Web Store to complete the installation. But, the mechanism has been abused by attackers to trick users into downloading malicious extensions.More news: Prince George pictured playing with a toy gun and people aren't happy
It may be more hard for malicious actors to get users to install their extensions directly from the Web Store. Also, Google will entirely block the inline install API from Chrome 71 in early December 2018 to completely remove it from developers' options. Google has not published information about the ratio of installs.
