You've led me to ESR 52.5; how can I download it, so I can use Silverlight?

A novice, with little computer skills. How do I download (step by step), etc. Using "Edge" browser on Windows 10, because don't want to screw up Firefox 57.0, also running.

This might be a little complicated.

Could you check the location of your Firefox 57 installation? If it is not in the 64-bit folder

C:\Program Files\Mozilla Firefox\

but is in the 32-bit folder

C:\Program Files (x86)\Mozilla Firefox\

then I think you might need to uninstall Firefox 57 first, and reinstall it into the 64-bit folder.

That will make space for the 32-bit Firefox 52.5esr to install into the 32-bit program folder.

Otherwise, I don't think the two releases can coexist. And to be honest, I have never tried this. (I can try it tonight on a secondary system if you don't want to go first.)

The other thing is that you need a new profile for Firefox ESR. You definitely do not want your two Firefoxes to share your main profile because certain files have a different format starting in Firefox 55. But that's another story...
