I have version 56 (32 bit) but I cannot install Silverlight.

Hello! I need to add Silverlight as an add-on, however everything I have atempted to do is not working to add it. Please, how do I place it as an add-on? If it is no longer supported, then what is the Firefox-approved add-on that will open a Silverlight application which I can add to my version? On another note, why did you guys remove it as an add-on if it is a universally-used application? It just does not make much sense.

Thanks.
