When I go to a site that contains Flash content, it says "A plugin is needed to display this content" and there is a link to install the plugin. Additionally, there is a message at the top of the page that says "Additional plugins are required to display all the media on this page" with an option to "Install Missing Plugins." I click the link to install the missing plugin, and a dialog box pops up that says "The following plugins are available:" and lists "Adobe Flash Player 220.127.116.11" with a check box next to it. The box is checked, and I click "Next" to install. It goes through the motions, and then tells me that "No plugins were installed." There is a link to manually install the plugin, which takes me to Adobe's Flash download page. I unchecked the box to pair McAfee Security with the download, and downloaded the latest version of Flash (to be honest, I've actually downloaded this exact same version about 10 times today). The dialog box pops up, I save the file, and once it has downloaded, I open the containing folder (my downloads folder). I then close all programs (including Firefox) except for the Windows Explorer folder that I'm going to run the installer from. I double-click on the Flash installer to run the installation. The installation process completes, the installer tells me that the download is successful, and my browser opens back up with an "Installation Successful" message from the Adobe website. Yay! My installation is successful... Orrrrrr not. Navigating back to the page with the Flash media - still have a message saying I need the plugin. Attempt to download plugin again...no dice.
THEN, I go to "Manage my add-ons" thinking maybe I need to enable the plugin. There is no Flash (or Shockwave) plugin listed on any of the menus - it's like it doesn't exist.
I downloaded the latest version of Java because I read somewhere that Flash requires Java to work; I installed the "Add-On Compatibility Reporter" so I could force Java to be enabled. It made no difference whatsoever, as best I can tell.
I also went to Adobe's page where you can see what version of Flash you're running (http://www.adobe.com/software/flash/about/) and it doesn't even show that I have Flash installed. In Internet Explorer, it does show that I have Flash installed, but it's the previous version (but that is likely due to the fact that I downloaded Flash from Mozilla, not IE, and they use different modes in each browser - so an update that you download from one browser does not necessarily apply to the other browser).
So in summary: I do not know what on earth is wrong here, but I am about as frustrated as I have ever been in my life. I don't know why the Adobe Flash installation is saying it is successful (is it lying to me??), but there is no plugin showing up in my Manage Add-Ons menu, and I have googled every possible combination of the content in this post and have not found a solution that works yet.
