There are two versions of Flash, one for IE (ActiveX) and another (Plugin) which is used by other browsers, such as Firefox. I don't see the Flash plugin in your list of installed plugins.

1.Download the Flash setup file from here:
Adobe Flash - Plugin version.
Save it to your Desktop.

2. Close Firefox using File > Exit
then check the Task Manager > Processes tab to make sure firefox.exe is closed,
{XP: Ctrl+Alt+Del = Processes tab}

3. Then run the Flash setup file from your Desktop.
