Flash Plugin is not installed and/or website do not display properly
Symptoms
When you open a website, parts are not properly displayed and you might receive additional messages such as "Flash Plugin is required to view this website".
Cause
In general, the Flash Plugin for Firefox and the Active X Flash Plugin are both installed and usable.
You can test this yourself: Open a browser and view the page http://www.adobe.com/software/flash/about - if the animation loads, the Flash Plugin is installed.
More likely, the cause is the installed Add-on called "NoScript".
How to get the website to display properly
If you open a website containing scripts such as Flash animation, javascript etc., the scripts are blocked by the NoScript Add-on.
