The HTML5 client for VMware is missing some functionality so I need to run the Flash client in Google Chrome. I normally run the Canary or Dev channels of Chrome and the ability to add or block a sites ability to run Flash seems to have disappeared from Settings -> Advanced -> Content Settings -> Flash. It is still there in the Stable channel. My default Flash setting in all is "Ask First", but nothing happens in Canary and Dev As per the instructions on: https://support.google.com/chrome/answer/6258784?co=GENIE.Platform%3DDesktop&hl=en The site needs Flash to work If a website isn’t working, you might need to change your settings to allow Flash. To the left of the web address, click Lock or Info . At the bottom, click Site Settings. In the new tab, to the right of "Flash," click Allow. Go back to the site and reload the page.
