Hey, I found this post while looking for help with Microsoft Silverlight. I have recently changed browsers from Google Chrome to Mozilla Firefox 3.1. After the change I seem to have a issue with loading sites that have Microsoft Silverlight. Every time I go on a website that requires Microsoft Silverlight, the site crashes and I get a “npctrl.dll” error. I cannot seem to find out how to fix it. Any help getting Microsoft Silverlight to work is very appreciated! Thanks
