Silverlight plugin is crashing when using Firefox v41.0

When working in GIFTS Online, Firefox v41.0.1 users may experience crashes related to the Silverlight plugin.

Silverlight Plug-In may be busy, or may have stopped responding. You can stop the plugin now, or you can continue to see if the plugin will complete.
This error has been resolved with the latest release of Firefox version 42.0. The steps below should only be used if you are unable to install version Firefox version 42 for an unrelated reason. 


This issue is caused by a recent Firefox update version 41.0.1, versions of Firefox prior to this update have not displayed the same behavior.
