I just uninstalled Flash, then did a pretty good search of all things adobe/macromed/flash in the registry and files. Saw parts installed both in IE8, which is my default browser, & in Firefox also - which I seldom run. Its doubful I have ever installed flash in firefox, no reason to ... yet it was there.

Going back to my tech support days, you need to clear your flash cache, if you are on a page containing flash you can right click on it and get into your flash control panel that way, there might even be a control panel for it settings>control panels, lastly if I recall somewhere on the adobe flash download page I think on the left there is some sort of settings option there, click on it and it'll have a bunch of tabs. You probably want to clear the cache out and see if that helps. You could also try add/remove programs, uninstall it, reinstall/reboot. Have you edited your registry before? Did you back it up first, to a separate disk? You can do very bad things messing with your registry if something goes wrong.
