There are other things that need attention. Your System Details List shows multiple Flash plugins.

1. Shockwave Flash 18.0 r0
2. Shockwave Flash 19.0 r0

You can find the installation path of all plugins on the about:plugins page.

You can check the Flash player installation folder for multiple Flash player plugins and remove older version(s) of the plugin (NPSWF32) and possibly (re)install the latest Flash player.

• (64 bit Windows) C:\Windows\SysWOW64\Macromed\Flash\

No same computer, I downgraded back to Firefox 28.0 to see if it would resolve the issue but it didn't. The version I upgraded to was 39.0.

This happened once before when I upgraded the Silverlight plug in, I did a system restore and that fixed it. Tried a system restore this time but it didn't fix it.

My operating system is Windows Vista.

Thanks for the info on Flash player. I had 4 or 5 versions of flash plug in before, downloaded flash uninstaller then uninstalled and installed the latest version but 18 would still show up, tried it twice and 18 would get installed with 19.
