Why is VM options greyed out in vmware web client?

Question : I want to open the console for the guest OS on a VM in Vsphere using Firefox on OSX. Everything is working properly on the machine. I am able to console using the desktop client program in windows -- but when I go to try to open the console in web client on OS X, the "Open console" button is greyed

Answer : This is not available when client integration plugin is not installed or blocked by the popup blocker. So if not installed install it and if installed check the popup blocker settings to resolve this issue and once done refresh the web browser.
