Adobe says I have latest Flash Player installed but it's not listed in program list and a video souce says I need to download it to open their video.
I can't open some videos--they say I need Flash Player but Adobe says I have successfully installed the latest 64-bit version. It doesn't show in the list of all programs but it is on the "uninstall" list. I have uninstalled the old version
Flash Player works if I use Explorer or Chrome

Your More system details list shows that you have the Flash plugin installed.
- Shockwave Flash 11.1 r102
If the Adobe test page confirms that Flash is installed and working then you may have an extension that is causing problems.
Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
- Don't make any changes on the Safe mode start window.
