I have been able to view Flash properties in Firefox, but it was not always this way. I've never really tried to view Flash properties in Firefox until today, due to only recently having started using Firefox. Initially, if I right clicked on Flash, Settings was greyed-out. I selected About Adobe Flash Player 9, which opened a Firefox window for Adobe Flash Player. I progressed to two other pages on Adobe's site, came back to the Yahoo page, from which I had first tried to open Flash player settings, right clicked on the Flash component in the page again, and, this time, Settings was available. I made a screen print, which can be seen >
