I gather this has become a problem with Firefox, so I'm late to the game. I want to use Silverlight 64-bit with a mapping program that requires it, but have not been able to get Silverlight to work with Firefox (I have 64-bit Firefox v59.x and W10). Anyone out there have a suggestion?

Why do Java, Silverlight, Adobe Acrobat and other plugins no longer work? https://support.mozilla.org/en-US/kb/npapi-plugins

Only the Firefox 52 ESR still allows other NPAPI Plugins to run besides the Flash Player Plugin from Adobe. For Windows if you use Win64 Firefox 52 ESR then only the 64-bit Flash Player and Silverlight NPAPI Plugins will run.

I read this Mozilla article before I posted my question. When was it written? It doesn't fully and clearly answer my question.

All plugins, except for the flash player, are no longer allowed in Firefox.

The article does mention that you can (for now) download the Firefox ESR version (for Silverlight you can use both 32-bit and 64-bit) from here :

It does if you read the last part.

Does not matter when it was written as it gives the needed information.
