I’m trying to run a program that requires silverlight and newer versions of Firefox don’t allow plug ins from silverlight. I have found a list of older versions of Firefox on Mozilla’s website but Once I click on a specific version several downloadable links pop up. Do I need to only download one link or several? Once I download the link do I have to move it to my applications or somewhere else to gain access to it?

Thanks for asking. The different links found on https://ftp.mozilla.org/pub/firefox/releases/ relate to different version numbers of Firefox. Once you open one of the version directories, you will see other links as well. You only need to download the version for your operating system (assumingly, you're using windows) so you will want the win64 or win32 version based on which version of Windows you are running (download the win64, if not, your computer will support the win32). You will need to know which version of Firefox allows the use of Microsoft Silverlight. Hope this helps!

Hi jpbutler51, the only currently supported browser that runs the Silverlight plugin is Internet Explorer 11. Please check with the vendor on how you are supposed to use their application in modern browsers.

I think there are some programs for Mac that you run Windows XP in a virtual machine, but I don't know the details. That could be a workaround.

Note: Some versions of Quantum change how the data files are set up, so they are not backward compatible.
