If Flash is not installed, this may trigger the Plug-in Finder Service, which you can use to download and install the Flash plugin on Windows ( see below). To see if the Flash plugin is working and what version is being used, visit one of these pages: Note: If the Flash plugin is installed, make sure it is enabled in the Firefox (3.0 and above) or SeaMonkey 2 Add-ons Manager ( see above) otherwise, the Flash test will not work and the "Shockwave Flash" plugin entry will not be displayed in the about:plugins list. If you have installed the Flash plugin but it does not appear in the Add-ons Manager, open about:config and make sure that the preference has not been set to "false" (if it has, right-click on it and select Reset to set it back to "true"). Note: On Windows, the Flash plugin is detected via plugin scanning. If the Flash plugin is disabled, click the "Enable" button to enable the plugin.
