Hello,
Potentially separate issue: you have an outdated version of flash. You can download an update https://get.adobe.com/flashplayer/
Not sure whats causing the script to not work for you. Do you have any extensions like NoScript or RequestPolicy that might be blocking it from loading properly?
You can also try to see if this extension will work for you: https://addons.mozilla.org/en-US/firefox/addon/adfly-skipper/
