You can also manually add or block websites on this menu by clicking the “Add” button and typing in the website you wish to add or block from using Flash.
If you see an error that says “The site needs Flash to work,” click the padlock icon (or “i” in a circle) on the left side of the address bar, click Site Settings, click the down-arrow, and then select Allow. When you reload the page, the Flash game, animation, or other content should appear. Chrome resets your Flash settings when you shut down the browser. This means that every time you come back to this website, you’ll have to allow the Flash to run again.
