Google Chrome version 69 is the 10th anniversary edition.  Improved Adobe Flash security controls are noted in articles below:

The latest version of Google’s Chrome browser doesn’t just bring a new, lighter look for its tabs: It also comes with a fresh set of handcuffs for Adobe’s Flash player. This update to Chrome, released just after the 10th anniversary of that browser’s debut, requires you to grant a site permission to run that multimedia plug-in after each restart of Chrome. Each time you visit a site that requires Flash, you’ll have to click a “Click to enable Adobe Flash Player” button, then click an “Allow” button at the top-left corner of the browser to enable that content to play.

Adobe announced last July that it would stop updating Flash at the end of 2020, essentially agreeing with critics that Flash’s history of security flaws that require frequent patches had left it unredeemable. And Google, having spent years trying to secure Flash with such measures as confining that plug-in to a protected “sandbox” isolating its code, is now moving more aggressively than competing browser developers to shoo Flash into the sunset.
