Is this a regression from previous versions of Firefox? NPAPI and Silverlight are considered legacy technologies and so it's unlikely that we would diagnose or fix this unless it's a regression in Firefox.
If this were a W64 bug I'd say it's a dupe of bug 1187005. But the WOW64 string in the UA means "32-bit app running on a 64-bit OS" so I'm less sure. Reporter: In the "Plugins" tab of your add-ons manager, is Silverlight set to "Always Activate" — or to something else?

The previous versions of Firefox were working fine. This problem has just appeared with version 42. Silverlight is set to "Always Activate" in the "Plugins" tab of my add-ons manager.
I'm marking this bug as WONTFIX per bug #1269807. For more information see - https://blog.mozilla.org/futurereleases/2015/10/08/npapi-plugins-in-firefox/
