Having issues with Adobe Flash player hanging the browser

Having issues with Adobe Flash player hanging the browser.

WIN 7 enterprise 32 bit / Firefox 19.0.2 /

Internal company website keeps giving attached screen shot error, and hangs the browser when error pops up.

Steps taken:

1. Uninstalled Adobe Flash player with the file “uninstall_flash_player.exe”
2. Deleted provided directory in instructions
   • "Copy and paste the following and click OK.
   • C:\Windows\system32\Macromed\Flash        
   • Delete all the files in this folder."
3. Rebooted PC and reinstalled the flash player directly from “http://www.adobe.com/support/flashplayer/downloads.html”
4. Re launched company website and received same error.
5. Repeated above steps as well as uninstalled Firefox browser.  Even went so far as to remove all profile information to start fresh from all profiles on the laptop with the same results.

Note: The web page will work without the flash player plugin, and my page doesn’t hang the browser. Required to open page in FireFox per company policy.
