McGee software ?? Sounds like a fake update message, to get you to install something that may be harmful. -------------- As it is, you seem to have two separate Flash plugins installed for Firefox. That can cause issues. IMO, the best thing to do is to completely remove Flash and then reinstall the latest version. First, grab the Adobe uninstaller from here: http://helpx.adobe.com/flash-player/kb/uninstall-flash-player-windows.html Then download the latest Flash Plugin version from here: Select ''Plugin-based browsers'' - the EXE version. https://www.adobe.com/products/flashplayer/distribution3.html Run the Flash uninstaller program, then reboot your PC. Then install the Plugin version of Flash. So you'll have a clean installation of Flash for Firefox.
