After messing with the global settings panel for Flash Player, I find I have somehow managed to make it so many Flash-based games simply don't play for me anymore in either Firefox or Safari. What preference files etc. do I need to trash from my Mac in order for Flash Player to be reset to fresh-from-the-factory settings? OSX 10.6.4.
On Windows you delete folders
On Mac OS there are probably similarly named folders, but I don't know where they are. Check the Flash Player Admin Guide if you can find the exact location in there.
