Step 1: Go to Content Settings
Rather than being forced to navigate through menus, the easiest way to access Chrome settings is via the address bar. Enter chrome://settings/content into the address bar and press enter.
Step 2: Scroll to the Flash tab
Towards the bottom of the Content Settings menu, under JavaScript, you will locate the Flash tab. Select it.
Step 3: Turn off “Block sites from running Flash.”
Once you turn off the “Block sites from Running Flash” button, you’ll notice the feature is now set to “Ask first.” From this point on, when you encounter a Flash plug-in, you’ll be asked if you want to activate it for that particular site. Also remove any sites you want to run Flash on from the section titled "Block sites from running Flash"
