I cannot get Microsoft Silverlight to appear as an add on to Mozilla Firefox. Have tried 1. Normal installation and standard instructions - install firefox 53.0.3 (32-bit) , silverlight 53.0.3 (32-bit). 2. Using Ninite installer and Mozilla refresh

Hi   Phil123456,

The regular release of Firefox 52+ only allows one plugin, which is Flash. The Extended Support Release (ESR) of Firefox 52 will still run Java and other old plugins. ESR was first developed to meet the needs of large organizations that wanted Firefox to change much more slowly. It gets security updates but no feature changes for about a year at a time.

You can download the ESR version from here :

https://www.mozilla.org/firefox/organizations/all/

More information on this change and ESR:

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

As a footnote to the above: When you get to the ESR installer list, you'll notice two or three different downloads for Windows: • Windows installer is the standard version for Windows that runs on both 32-bit and 64-bit Windows 7-10 • Windows 64-bit installer ONLY runs the Flash and Silverlight plugins. (If someone reading this only needs Silverlight and is considering switching to 64-bit, there may be some extra file cleanup to do on your system. See: How to switch from 32-bit to 64-bit Firefox)
